Netflix pulled the trigger today and finally completely ended its relationship with Marvel by canceling both The Punisher and Jessica Jones. It wasn't really a surprise since the cancellation of Daredevil -- arguably the most popular of all the Marvel Netflix series -- showed the writing was on the wall.It also seems bittersweet.Jessica Jones was a critical darling, Daredevil rebounded from a slight drop in Season 2 to produce a great third season and even Iron Fist had fans excited with the marked improvement of its second outing after a critically disappointing first season. The question remains -- where did it all go wrong?RELATED: Hulu Open to Reviving Canceled Marvel Netflix SeriesThe answers are numerous, but the fact is that both Disney and Netflix were equally to blame. Disney wanted so much more, and its creation of the Disney+ streaming platform ensured it could keep almost all its movies and TV shows in-house, maintaining complete control.Netflix, on the other hand, had grown so much -- especially concerning original content -- that it might have outgrown Marvel. Between the massive success of original movies like Bird Box and series like The Haunting of Hill House, the seeds were planted that it might not need to bother with Marvel or Disney anymore.Netflix, in the announcement of the recent cancellations, made it clear that the Marvel shows already produced were not going anywhere, saying: "We are proud to showcase their work on Netflix for years to come.” That makes it clear that fans shouldn't expect to see the previous seasons of the Marvel Netflix shows popping up on Disney+.But what does Marvel think of this? Jeph Loeb said that he would not be surprised to see any of the Marvel Netflix shows coming back somewhere else in the future if the showrunners and cast were available to revive them. Whether this is on Disney+ or Hulu, that at least provides a glimmer of hope for fans of the canceled series.But why couldn't Marvel and Netflix make things work? Both sides have pointed fingers, but the truth rests somewhere in the middle. Marvel can now keep control of its properties and Disney can gather everything it can in-house. On the other side, Netflix was clearly bothered that Disney was yanking all its movies when Disney+ debuts, so canceling the Marvel shows was seen as almost a retaliatory move.After Netflix canceled the first three Marvel series last year, Daredevil co-executive producer Sam Ernst made it clear that it wasn't Marvel or Disney that was to blame, but Netflix. He said that the writers even had Season 4 completely laid out when the news came that the show was axed.

Amy Rutberg, who plays Marci Stahl on Daredevil, said something similar when she said her contacts at Marvel were very surprised and that it was "a Netflix decision."

If this is true, then why would Netflix -- who said that numbers were still good, especially for Daredevil -- cancel Marvel shows while the MCU was still at the height of its popularity? Avengers: Infinity War is the fourth highest-grossing movie of all time, and the DCEU production Aquaman proved that superhero fatigue doesn't really exist when it broke $1 billion worldwide.

The truth is that Netflix was already looking to the future and was ready to break up with Marvel when the Disney+ rumors started circulating. By the time that Disney announced its streaming service and then acquired Fox, which brought it control of Hulu as well, Netflix had already started making its own plans.

Before Netflix canceled any Marvel show, it set up a huge deal with Mark Millar to bring his Millarworld productions to its streaming service. Netflix proved to be ready to move beyond its simple partnership with Marvel, agreeing to also produce Millar's comic books, with an eye on possible adaptations.

The Umbrella Academy

Umbrella Academy hit the streaming service this past weekend, and from all accounts it is a huge success. Umbrella Academy is from Dark Horse Comics, and alongside Archie Comics' The Chilling Adventures of Sabrina and the ongoing Millarworld projects, Netflix is working on something wholly original.

While there have been some major success stories for Marvel on the small screen, with Daredevil and Jessica Jones getting a lot of critical praise, and shows like Legion and the latter years of Marvel's Agents of S.H.I.E.L.D. hitting on all cylinders, it was still the movies that ruled the roost.

Netflix seemed ready for the divorce, excited to step out of Marvel's shadow and create something completely different. American Jesus, Jupiter's Legacy, Locke & Key and October Faction are just some of the non-Marvel comic book shows coming to Netflix in the near future.

As for Marvel, it is rebounding quite well. While Loeb has said that there will be a chance that the Marvel Netflix series could get future seasons somewhere else, Disney+ already has big plans for other Marvel superheroes.

Scarlet Witch and Vision have a series coming to Disney+, while the Loki series just named Michael Waldron as the showrunner for a series featuring the God of Mischief. The divorce was shocking to fans and to the creative teams of the Marvel Netflix shows, but it doesn't seem to be a bitter end.

The custody battle for Daredevil and company might heat up in the next year, but for now it seems that Marvel and Disney might be willing to wait out 2020, when Marvel regains control of these properties so it can start working on them again. For now, fans can just be happy to have received 13 seasons of great original Marvel content from Netflix before the two sides just outgrew each other.
