One of the most confusing things about plot holes is determining what is a "hole in the plot" and what is just a bad idea in the movie? What it really comes down to is a question of internal logic. It does not make sense that getting bitten by a radioactive spider would give you superpowers, but that it does so fits the internal logic of the Spider-Man films. Similarly, it seems unlikely that Peter Parker's stress over his powers in Spider-Man 2 would cause the powers to disappear, but it does not contradict the logic of the film that such a thing would occur.
A plot hole, on the other hand, does contradict the logic of the film. For instance, a minor one would be Doctor Octopus' fusion reactor in Spider-Man 2. It is shown to have a strong magnetic pull...except for the multiple times in the movie when it does not have a strong magnetic pull for no reason. That is a hole in the plot, a plot point that goes against the internal logic of the film. With that in mind, here are the 15 biggest plot holes in the five Spider-Man movies that have come out before Spider-Man: Homecoming, three by Sam Raimi and two by Marc Webb.
15 NOW YOU TELL ME
In Spider-Man 3, George Stacy calls Peter and Aunt May to his office to tell them some news. As it turns out, Flint Marko, who has escaped and is now the super-powered villain known as the Sandman, was actually the real killer of Uncle Ben! How does Stacy know this? Because Marko confessed to the killing while in prison in front of multiple witnesses. Why didn't anyone tell the Parkers this earlier, before he escaped? There is no reason given.
Not only that, but with Marko the real killer, it also makes the actions of the supposed killer in Spider-Man now make little to no sense. He never even got out a simple "I didn't do it!" whimper? Seriously? Obviously, it was a retcon, but they could have made it make more sense than that.
14 NOW YOU TELL ME (PART II)
In another instance where someone tells someone else very important information much later than they probably should have, Bertrand, the Osborn family butler, saw Norman Osborn die in battle against Spider-Man in the first Spider-Man movie, but then decided that he was just going to sit on that information. We would understand that logic if Harry Osborn wasn't so clearly struggling with what he believed to be a case of Spider-Man murdering his father.
Instead, he waited until Harry had nearly destroyed the city to let him in on the truth. Sam Raimi clearly realized that this made little sense, so in the original version of Spider-Man 3, "Bertrand" was just a vision in Harry's mind telling him what he already knew to be true, that his father was a bad man.
13 WORST SCIENTISTS IN THE WORLD
After escaping prison (while apparently broadcasting to the whole world about how he killed Ben Parker), Flint Marko ended up in a pile of sand that was, unknown to him, the setting of a unique particle accelerator experiment. That's reasonable enough, he certainly could not be expected to know that a pile of sand was a problem.
However, the scientists performing the experiment specifically knew that someone had landed in the middle of their experiment and they decided to just keep on going with their very dangerous particle accelerator! One scientist says, "It must be a bird. It'll fly away." First off, why in the world would you even take that risk? Secondly, how in the world would the weight displacement of a grown man be confused with a bird? Worst scientists ever!
12 LUCKY SECRET SUBWAY CAR
In Amazing Spider-Man 2, Peter happens to smash his father's calculator, which revealed a hidden subway token. This made Peter realize that his parents must have a secret lab at a secret subway stop. So Peter goes and finds a hidden subway station and, sure enough, Richard Parker had built a secret lab in a subway car in the middle of a secret subway station.
In that lab, he left a video message to his son to tell him about his past. So yes, in a secret lab in a hidden subway station that Peter could not possibly get to unless he broke his father's calculator, Richard left a message to fill his son in on things. Spider-Man often complains about "Parker luck," but damned if that wasn't some amazingly good luck right there!
11 AIN'T THAT A CRANE KICK IN THE HEAD?
At the end of Amazing Spider-Man, New York City is evacuated while the Lizard is on the loose. All of New York City, of course, except a bunch of crane operators, who are somehow all ready and close to their cranes despite, you know, cranes not actually operating at night. Not only that, but the cranes are all luckily located in just such a fashion that they can send Spider-Man from crane to crane to get to the Lizard.
Now, even if you accept all of that prior silliness, the end result is also that they don't even really help Spider-Man. He can clearly travel diagonally across the buildings, he had been doing so all throughout the movie! So the crane operators saved him, what, a couple of seconds tops?
10 THE WORLD'S MOST POWERFUL LOCKET
Once the world's worst scientists let the particle accelerator start up in Spider-Man 3 despite Flint Marko still being in the pile of sand (at least Marko didn't just stand there, he did try to escape but the process had already begun and he was trapped), his entire body was transformed and then bonded with the sand in the pile, turning him into a man made out of a sand, or a Sandman, if you would.
The transformation affected the particles in not only Marko's body, but also his clothes, right down to his belt buckle. And yet, somehow, it did not affect the locket from his daughter that he was carrying in his pocket. The movie doesn't even slightly try to come up with a reason why it happened this way.
9 GWEN STACY, ELECTRICAL GENIUS
Towards the end of Amazing Spider-Man 2, Electro has teamed up with Harry Osborn and helped him break into Oscorp to gain access to the Spider Venom and other weapons that his father had left him. Once Harry was done, he gave Electro the go-ahead to use the special electrical grid that Electro had worked on back when he was an electrical engineer at OsCorp to take over the electricity for the entire city of New York.
When Spider-Man headed off to stop Electro, Gwen Stacy insisted on coming with. Why? Because somehow she was an expert on the electrical grids of New York. As lame as that already is, the real kicker is when they get there and the way to re-start the grid is literally to press a giant button. Wasn't Spider-Man lucky he had an "expert" along with him?
8 WHAT'S THE DEAL WITH THE COSTUME?
In the Sam Raimi Spider-Man films, Peter Parker is noticeably poor. The guy doesn't even have his own telephone! He had to use a pay phone to make phone calls! Yet, despite not making any money, Peter is able to afford what appears to be very expensive material that he uses for his Spider-Man suit. And don't forget, this is a suit that repeatedly gets torn up, so Peter is apparently a whiz with sewing and designing, and can afford to keep replacing the suit.
Even further, though, throughout the films Peter changes into Spider-Man, goes off and fights some bad guy at an entirely different location and then quickly changes back... to clothes that couldn't possibly be at his new location. Clearly, they presumed that fans wouldn't apply any real thought to this issue, and they were most likely correct. It's still a plot hole, though.
7 HARRY OSBORN, OCTOPUS GPS
In Spider-Man 2, Harry Osborn cuts a deal with Doctor Octopus. Harry will give Octavius the isotope tritium that Octavius needs to power his reactor in exchange for Octavius delivering Spider-Man to Harry, as Harry blames Spider-Man for the death of his father in the first Spider-Man film. Octavius agrees and then manages to capture Spider-Man and makes the trade with Harry.
Harry then unmasks Spider-Man and is shocked to learn that Spidey is his best friend, Peter Parker! When he captured Spider-Man, Doctor Octopus also captured Mary Jane, so Peter convinces Harry to forget their current beef and allow him to rescue Mary Jane. Harry agrees. Peter than asks Harry where Octopus' secret lair is and Harry tells him -- despite Harry never being there and never talking to Octavius about it!
6 LIZARD'S PLAN IS A LITTLE GREEN
In Amazing Spider-Man, Curt Connors is naturally a little bit nutty. However, that still doesn't quite explain how little sense his master plan makes. Connors' plot is to douse the entire city with the chemical that transformed him into the Lizard so that they will be transformed, as well. However, as we established earlier in the film, since Connors (and everyone else's) DNA is not special like Peter's DNA was, the effect will be just temporary.
So what, exactly, would be the point of him dousing the city and temporarily transforming everyone into lizards? What would possibly come of that? What is the benefit for him? Yes, he has been driven mad, so that excuses a lot, but even a crazy guy should know that that plan doesn't make any sense.
5 REALLY BAD REAL ESTATE DEAL
One of the strangest things about the introduction of Otto Octavius in Spider-Man 2 is that he has a harness with super-powerful arms that he can mentally control and no one seems to particularly care. They're all, "Just show us your fusion power project! Who cares about those arms that are obviously gigantic scientific breakthroughs!" That, though, is not the biggest logical failing in the scene.
No, the biggest leap is that the fusion power project is taking place in the middle of a skyscraper in Manhattan! Who in the world would possibly authorize such a dangerous experiment in a skyscraper in the middle of the most densely populated city in the United States? Later on, when he goes on the run, he had the next experiment take place on a pier, which makes a whole lot more sense. So he had to become a supervillain to be more careful with his surroundings?
4 PROPERTY OF STUPID
Historically, Peter Parker takes photographs of his battles as Spider-Man and sells the photos to the Daily Bugle, where J. Jonah Jameson uses them to try to make Spider-Man look bad. It's all horribly unethical, but it's a major aspect of the character's history. That was not the case in Amazing Spider-Man, but Peter did own a camera.
The problem, of course, is that despite having the foresight to come up with a costume that had a full face mask to disguise him to make sure that no one learned his identity, Peter carried around a camera in his Spider-Man identity that had labeled on it..."Property of Peter Parker." Okay, maybe that the famous "Parker luck" we have heard so much about.
3 THE TRENCH-COAT OF INVINCIBILITY
Doctor Octopus is a formidable opponent, as his powerful mechanical arms can lift cars up and throw them with ease. He can crush right through buildings. He's quite a scary foe. However, what the arms did not do was change Octavius himself, at least not physically. He was still a middle-aged man... in an awesome harness.
That is why it did not make any sense that Spider-Man (he of super strength) could pummel Octavius repeatedly in the face without it actually successfully knocking Octavius unconscious. Often, in the film, Octavius' arms protected him from Spider-Man's attacks -- that would probably have been best to just keep that up throughout the film and not let Octavius withstand a super-strength punch.
2 RICHARD AND MARY PARKER SUCK
As we learned in Amazing Spider-Man 2 (via Peter discovering a secret video left for him in a secret lab in a hidden subway stop that he never could have found under normal circumstances), Richard and Mary Parker felt that Norman Osborn would have them killed due to their genetic research, so they decided to go on the run and leave their son, Peter, behind for his protection.
However, they did not change his name or do anything to protect him besides leave him with his aunt and uncle, so even if Richard and Mary had escaped, wouldn't Osborn just go after Peter? Their plan made no sense. Not only that, but as we saw in the first Amazing Spider-Man, it was no secret that Peter's DNA worked with the spider's; therefore, Peter was an even greater target in the eyes of someone like Osborn!
1 A CAB WILL ALWAYS GET THEM TALKING!
As noted earlier, in Spider-Man 2, Harry Osborn cut a deal with Doctor Octopus. Harry would give him the isotope he needed for his reactor and Octopus would give Harry Spider-Man. How would Octopus do this? Harry explained that his best friend, Peter, likely knew how to find Spider-Man, so Octopus could ask him, but Octopus was not allowed to hurt Peter.
So Octopus, who needs Peter's help to find Spider-Man, finds Peter and Mary Jane (how he found them is also a mystery) and then throws a cab at them! The only reason they don't die is because of Peter's Spider-Sense, which Octopus doesn't know he has because he doesn't know he's Spider-Man! It's one of the most ludicrous plot holes of all-time!
