Comic book wise I have always been DC over Marvel, but I can't deny that Marvel have a much more developed cinematic universe. I find that with the Marvel films they are either great (Iron Man, Winter Soldier, first Avengers movie) or utter rubbish ( Iron Man 3, Avengers 2, Thor 2).
DC movies (so far) I think are trying to capture something which translates well in comic book form, but for the cinema just seems like a lofty vision which has just missed the mark due to poor scripting or editing.
