Fans of Yakko, Wakko and Dot were delighted that Rob Paulsen, Jess Harnell and Tress MacNeille were confirmed to reprise their roles for a revival of Animaniacs. With Steven Spielberg also returning as executive producer and Maurice LaMarche reprising his role as The Brain, the show looks to be keeping true to what made it great in the 90s, while also having 22 years worth of new material for laughs.

Like other entertainment properties in the 90s, Animaniacs pushed the envelope in their humor, artwork and subject matter, making it funny for adults and kids. That is one of the reasons why it is fondly received today, since the kids who watched it during its original run have grown up and can now appreciate the humor that once went over their heads. While it is unclear which recurring characters and segments will return this November, it may be for the better if certain characters don’t make a comeback.

Slappy Squirrel

Slappy was a caring aunt to her nephew Skippy. While she did solve her problems with exaggerated cartoon violence, this most likely won't be a problem since current Warner Bros. shows like Teen Titans GO! and the revived Looney Tunes feature this as well. The real problem with Slappy is that she outsmarted her adversaries way too easily at times, lessening the stakes in each sketch, as well as the credibility of her rivals. Even though that was the point of most of her sketches, today’s audiences are accustomed to the stakes being higher than what Slappy allowed her enemies to have. Furthermore, having a rival named "Beanie the Brain-Dead Bison" doesn’t help her case.

The Goodfeathers

It has been confirmed that Maurice LaMarche will be reprising the Squit character, which is based on real-life gangster and Goodfellas protagonist Henry Hill; however, Squit’s friends Bobby and Pesto, parodies of Robert De Niro and Joe Pesci, will not be returning. While the "Goodfeathers" worked in the 90s since both Goodfellas and The Godfather III were riding pop culture waves, the most recent popular mafia drama millennials would have watched is The Sopranos, which completed its run 13 years ago, making references to that genre a little outdated.

Mindy and Buttons

Another one of the repeatable formulas in Animaniacs, the viewers always knew that Mindy would return safely from her adventures. The viewer also knew that "Lady" and "Mr. Man" would scold Buttons for something minor or for something he did not do, while not knowing he did everything possible to keep their daughter away from harm. Even though suspension of disbelief is needed for any show, the fact is Mindy’s parents often left her home alone with a dog as a babysitter. They may be seen as unjust and judgmental in the way they scold Buttons, but mainly they could be seen as irresponsible and unfit parents.

Rita and Runt

These sketches featured Bernadette Peters, one of the greatest musical theater actors of her generation, whose beautiful, timeless voice gave life to Rita, the cat companion of Runt the dog. What could work today is the male-female friendship of Rita and Runt, which was and is still relevant for today’s audience; however, musical theatre has grown so much since Animaniacs ended that keeping Rita true to her original portrayal would be limiting for the character and Bernadette. Also, keeping Runt oblivious to the fact that Rita is a cat does not offer anything new to their relationship. Originally it would have been seen as a charming dynamic since Rita and Runt had mutual love and respect for one another, but today, some may look at their dynamic as disingenuous and opportunistic on Rita’s part.

Chicken Boo

He’s the chicken who, "wears a disguise to look like a human, guys," and he roamed around the country, sometimes doing heroic deeds and making a positive contribution to society. One person pointed out the fact that he’s a giant chicken, but he was deemed crazy until typical hijinks cause Chicken Boo to be exposed for what he is. Once the jig was up, all the good things Boo did was forgotten, and he was shunned for not being human, a concept that does not fit in well with the ideas of tolerance that are in today's cultural consciousness. Although he did get some development and had episodes that deviated from the standard format, the joke got old and uninteresting in mainline sketches.

Flavio and Marita, The Hip Hippos

While the concept of a loving and loyal married couple who are looking for new experiences outside of their comfort zone is a safe concept to go with, what makes the Hip Hippos not so great for this time is how their affluence makes them unrelatable characters who are disconnected from the problems of society. Furthermore, even though they have no issues with their larger sizes, the jokes could come off as fatphobic.

Katie Kaboom

The trope of the teenager dealing with adolescent emotions is taken to a ridiculous level with Katie, a girl whose temper literally blows up like a bomb when she’s emotionally triggered. While it’s taken to the most exaggerated level possible, which was impressive even for a cartoon, where it became problematic was the connotation of Katie fitting the "crazy teen girl" stereotype, or the sketch could be construed as insensitive to mental health. Her sketches also suffered the same problems as the standalone Chicken Boo sketches, where the format was always the same, and the character were never really developed.

Minerva Mink

Even in the 90s, where nearly everything was attempting to push the limits of what could be shown, parents were pushing back on Minerva Mink because of her hyper-sexualized portrayal. Characters that fawned over her did so in the classic Tex Avery, wild-take style, and, as part of the joke, she reacted the same way when she saw a hunky dude. Today, Minerva's suitors could be construed as thirsty, desperate and creepy. Minerva might also be seen as a manipulator, gold-digger and one-dimensional, especially since she never got a chance to show more than her sexuality.
