I just got done watching the newest Batman movie (Batman begins). And while it was interesting and kept my attention for the most part I don't think it was nearly as good as the latest Spiderman movies. The characters in Spiderman I think are alot more developed and interesting than the characters in Batman are.
Spiderman's characters seem to be alot more real (they act in alot of ways like people in the real world would act). Where as the characters in Batman just seem to be kind of fake in a way (probably due to the fact that they live in a make believe place so they don't really have to act just like us).
So which movies or comic book series did you like best. Maybe there are some folks who like Superman as well. But I think Batman and Spiderman are considered to be the two most popular so that is why I compared them to eachother more so than Superman (plus Superman's movies are about twenty years old now).
