I am a HUGE Batman fan. Since a kid, he's always been my favorite. I liked him, because unlike other Super-Heros, he didn't have super-powers. Both his parents were killed, and instead of letting that tragic event make him into a monster, he used it to better himself.
He trained hard, studied, and made himself the best possible at what he did.
I liked Batman '89, but I didn't think it was the most accurate depicition of Batman. They made Batman more like Iron Man, where was just some average guy(Keaton) that got into a super-suit and fought crime.
I liked Begins, because showed Bruce's training and what he had to do to become The Dark Knight. Plus, Bale I think was the closes to how I saw Batman.
