For me, I feel differently about all of these studios. Marvel has a very, very good track record so far. They haven't made a truly bad movie yet, just a couple of not-terribly good ones *cough*Iron Man 2*cough* I actively look forward to their movies, even the ones based on characters I know very little about. I mean, the Inhumans? They sort of sound like a Marvel-ized version of Nightbreed... okay, why the heck not?
I'm of two minds on Fox. For one, I've thoroughly enjoyed their last several X-men movies, and I want them to keep the rights for as long as possible. That's saying a lot coming from me, considering how much I disliked The Last Stand and Origins. Now, Fantastic Four... I have no idea what to think, largely because I don't a single freaking thing about it yet. Educate me, Fox. I want to give you the benefit of the doubt here.
Warner Brothers is a bit of an unknown factor here, and that's actually pretty intriguing in my opinion. At this point, we really can't say what most of the movies are going to be like, or how good they'll be. That's a total gamble, and I find it exciting. And it helps that Suicide Squad is sounding better and better all the time. Oh, and Jason Momoa as Aquaman? As a fan of that character, I'm thrilled that he'll be a certified badass on film.
And Sony... oh Sony. I hate saying bad things about them, since I actually liked the Amazing Spider-Man films. That being said, they are seriously going full retard on this. Instead of dropping their habit of screwing with the movies, they fire Andrew Garfield for calling them out on it. Seriously, WTF? He's one of the best things you have going with these movies. And making a cinematic universe around a single character and his supporting cast is just stupid.
