I thought this was going to be a thread about the characters themselves in which case Batman would be the obvious answer. NeoCracker is spot on saying that Batman Begins is better than the three films in the poll though.

I, like a few others in this thread, would say it's really a toss up between Spiderman and Batman. The Spiderman films were decent enough, though not fantastic, but good enough for me to own two of them on DVD (the fact that they cost me £3 and £2 respectively is irrelevant). I'm not a huge fan of love stories being unnecessarily tacked into books or films or whatever, but I actually quite liked the love story of the Spiderman films.

On the other hand, Batman was a decent film too and as far as settings go, I preferred it to that of the other films. I prefer Batman as a character but I think, actually, I'm going to narrowly go for Spiderman. But only just. And I'll probably think otherwise tomorrow morning.
