Marvel is wayyyy better than DC because marvel has more superheroes! Think about it. Would you rather watch The Avengers, or The Dark Knight Rises. You decide. Honestly, I think marvel is better because of the Avengers, Fantastic 4, and Xmen. Wolvorine has freaking claws that come out of his hands!
I only collected Marvel for a really long time, then all those Marvel movies came out and I'm like.. Yech... They totally ruined my childhood memories of what those heroes and villains were like to me.
I agree, DC is much darker but I don't like their movies any more than Marvel. I just don't have the same memories for DC.
I'll take this moment to say, almost all the movies I've seen from Marvel and DC suck.
If I had to choose one would choose one. Not because I am fan of DC it's because DC is darker and has a more thought provoking messages. I do like Marvel Movies and I was a huge comic nerd at one time. The reason I stopped relying on these comics is because some of them will never ever end. Spider Man kept continuing for a long time before they decided to reboot. I get marvel has awesome movies but DC let's you think more.
By me saying that I hate both in the reason. They are terrible choice for me. I rather not care if Iron Man wins or Batman wins. You know why? Out of those heroes it'll always be writer's choice on who wins.
