Burton responded, "I like Batman Returns better than the first one. There was this big backlash that it was too dark, but I found this movie much less dark."
I think Burton's idea of 'dark', and the mainstream sense of the term are different. Batman was dark in the Shakespearean, theatrical sense. Batman Returns had a lot of really 'creepy' - though very Burtonian - psycho stuff. (There were elements of the same in his version of Willy Wonka.)
Not that I was bothered by it, but it seemed stark and cheap. Wishy-washy. There was no real poetry in Batman Returns, but rather adolescent carnival-ism, with a dose of 90s-era mayhem. It didn't seem an 'adult' film.
Not to mention the story was lugubrious and tedious. There are many scenes that speak 'deleted scenes', or would've been in a higher-class movie. And there was really little if any dialogue that was memorable, let alone provocative.
Well, that's not completely so. Catwoman had some good stuff - and Pfeiffer was a good fit - but perhaps only if you were male. None of it was remarkable, just lasciviously good....or goodly lascivous.
Yet, the love story was severely lacking, and the scenes depicting it had no pizzaz, quite unlike those between Bruce Wayne and Vicki Vale in Batman. I think both the Vale character and Basinger were stronger and far more provocative entities. Hell, it was probably a really bad idea to even have a love story in the Batman Returns.
Anyways, the movie was a lemon.
Interesting statements from some (prominent) reviewers:
Roger Ebert stated "I give the movie a negative review, and yet I don't think it's a bad movie; it's more misguided, made with great creativity, but denying us what we more or less deserve from a Batman story. No matter how hard you try, superheroes and film noir don't go together; the very essence of noir is that there are no more heroes."
Jonathan Rosenbaum called DeVito "a pale substitute for Jack Nicholson from the first film" and felt "there's no suspense in Batman Returns whatsoever".[34] Batman comic book writer/artist Matt Wagner quoted, "I hated how Batman Returns made Batman little more than just another costumed creep, little better than the villains he’s pursuing. Additionally, Burton is so blatantly not an action director. That aspect of both his films just sucked."
