Agent Richard07 has the right of it. These things are cyclical. A decade or two ago, it was DC that had all the hit movies, while Marvel fans were wondering why their guys couldn't get their act together and put out anything good. And even when we started to get good Marvel films like X-Men and Spider-Man, we still got duds like Daredevil too.
See the problem with that is, when DC was at its height, they only had one franchise going on and several DC franchises have never been adapted to film.
From 1978 to 1987 it was just Superman related films and that is it.
From 1989 to 1997, it was mainly just Batman films, the main exception being Steel.
We still have not seen a Flash movie or a Wonder Woman movie. Pretty well every major Marvel character has gotten a movie and now Ant Man and Guardians of the Galaxy are getting movies before Flash and Wonder Woman. That is the problem I have, even when DC was on top, they did nothing with a lot of characters, just focusing on their two big franchises.
