4. You're a fanboy
You know who are the least worthy people to judge something based on a comic book? Fans. Oh a black guy got cast as a white guy in Fantastic Four? You know who cares? No one but like, 7 comic fans because no one cares about Fantastic Four.
Point is, a fan is usually never fit to judge something because they already have a preconceived notion of how something should be. Having those preconceived ideas rules out the possibility for change that everything needs. It'd be a disappointing world to see the same Batman cartoon every year with no change.
3. It's an ACTION CARTOON
Everyone jumps to the conclusion that it's a new Teen Titans GO. But in fact, it's been described as an action cartoon. Is there any real problem with it being an eleven minute action show? Is that really something to gripe about?
2. You have seen essentially nothing
Just like every other comic adaption in history, people jump to conclusions at the first still they see. In fact, literally every superhero cartoon show in the past 7 years has had the same reaction. Beware The Batman? Spectacular Spiderman? All of these shows ended up great despite the negative backlash before release. What's to say this isn't the same?
1. A TON OF PEOPLE FROM THE DCAU ARE WORKING ON IT
Kevin Conroy, Mark Hamill, Bruce Timm, Paul Dini and more are involved with this new show. I really can't see how anyone can doubt the shows quality and complain about the changes when all the people from the old show are now working on the new one also. But y'know. Obviously just gonna end up like a new Teen Titans Go.
(which btw isnt a bad show you to be honest)
