I know I've adamantly defended it in the past, but I'll point out that my opinion of Superman Returns is not what it once was. I don't hate it or anything but I'm not really in love with it either. (The same thing has happened with the Spider-Man movies for me, I've noticed, though to a lesser degree.)
I disagree that Superman Returns did the exact same thing. If anything, the biggest problem most people had with it is that it devoted itself to a past interpretation of the character rather than making it it's own. The movie definitely had it's problems but I don't think it was the same as Burton's Batmans.
It's not as if I hate Batman 89, there's a lot about it that I like and I wouldn't fault anyone for loving it, it's just Burton's attitude towards the subject that annoys me. The problem, to elaborate, is that Burton seemed to care less about Batman as a character and more as a medium for him to keep exploring the same themes he explores in every one of his movies. That's fine and all, but when you're given the responsibility to make a movie about Batman, you should make it about Batman. The comics are full of a million different unique interpretations of the character but the movies are so few and far between, I just don't think we have time for that kind of thing.
One of the best aspects of Nolan's take on Batman is that - particularly in The Dark Knight - he seems concerned with the layers of ideas and themes that are already inherent in the characters and stories, rather than shoehorning the characters into the kind of story he wants to tell. I think Burton has a hard time understanding that just because he's the director doesn't mean the characters now belong solely to him. (Remember the horror of his possible Superman movie in the 90s...)
Batman 89 was a fine movie, but two Nolan films later, it can sometimes feel a bit like Burton cheated people, seeing now what's possible.
