Batman
The first one with Michael Keaton

Begins is good, but Batman wins purely out of Nostalgia, or TMNT, first or the new one.

Ooo, the old Batmans are good! And I loved the TMNT movies- I haven't seen them in so long

My favourite is a toss-up between the Keaton/Burton Batman, and Batman Begins. Can't think of too many I actually like.

My faves

1st 2 X-Men movies
Batman with Michael Keaton
Batman returns (although some of it was too dark)
Batman Begins
Spiderman

I'd say batman or batman begins, I cannot choose. Sin City might top them both if it counts, though. V for Vendetta might have come close, but I think the film was missing something vital. Can't put my finger on it, though.

If a film was ever made of The Invisibles, and done properly, I'd probably say that was the best, though.
