But that is your opinion. In my opinion a movie loses its tension the funnier it gets. I already get that with the Marvel movies. I don't need that from DC too.
Just because humor is part of our daily lives doesn't make it mandatory for a fun film. It seems like a lot of people don't get the difference between humor and fun. Yeah, I want fun in my superhero movies and I got much more fun out of the Dark Knight trilogy and MoS then out of any Marvel film, all of which have had a lot more humor. For me, it is fun to be thrilled and fear for the characters. Its fun to have huge dire stakes against the hero and see him overcome that. Undermining that with laughs is for me the wrong way to go.
As much as I enjoyed Iron Man 3, it had so much humor in it that I could not take anything in it seriously.
Apart from small doses of humor, like in Dark Knight or MoS, too much humor doesn't mesh well with drama and I want to see drama in a superhero film, not comedy.
Its the same in the comicbooks. The best ones take themself pretty seriously and provide drama without many laughs. Thats the way I want DC to continue making movies, since thehumor fans allready have their Marvel stuff to fall back on.
