I don't know but the DC comic characters seem to be boring movies. All of the Superman movies/tv was a pile of cow dung. Even Smallville after season 3 or so was painful to watch.
Batman with Keaton as Batman and Danny D as the Joker was the best, everthing else was subpar or downright horrible (yes I am looking at you George Clooney).
Green Lantern with Ryan Reynolds was horrible that I walked out of the theatre in the middle of the movie
Supergirl TV - looks to be another clunker. It's like Smallville but only more PG13
