It's actually one of the few live action Disney adaptations that I liked, which I'm totally against to be honest! But here's why: this one isn't a frame-by-frame of the cartoons that we saw as kids! It had more depth and more characters, and the side characters were well-written. Most importantly it's Michael Keaton (Batman) and Danny Devito's (Penguin) first reunion since Batman Returns in 1992, and also Tim Burton and Danny Elfman! I got to say I totally loved it!
PS: I'm a fanboy of Tim Burton's but I hated his versions of Alice in Wonderland, Frankenweenie and Dark Shadows. So I'm objective here.
