Yes, who wants sophisticated characters and story after all. And if you want 'fun' Batman, go and watch the 1960s TV series.
I have nothing against the Nolans Batman movies I just think they have influenced the genre in a negative way. Punchy comic book movies like Spiderman 2 are going to be replaced by arthouse movies essentially.
I like my comic book movies to be filled with two-dimensional characters where good and bad is clearly defined. Those movies are usually more fun and aren't stretching 3 hours in length.
