I vote Batman. I agree with everything said about Superman's importance and great filmmaking, but I also agree with the problems in the last hour and Lex Luthor, and those are deal breakers for me. Batman has issues as well, but it holds together for me and came out on my birthday when I was 7 and probably turned me into the comic geek I am, so I'm probably biased. (I am bias.)
I loved the comparison of Batman with Universal Horror, I've always thought that Batman Returns was Tim Burton's Bride of Frankenstein.
