Uh Oh here's something that might get you in trouble which one of these is better to you? Marvel has made way more TV shows and movies with theirs but DC still has its pints, it's up to you. Let's see all the films by both companies
DC:Superman, Batman, Batman Returns, Batman Forever, Batman & Robin, Batman Begins, Catwoman

Marvel:Spiderman, Spiderman2, Blade, Blade 2, Blade Trinity, The Hulk, Dare Devil, X-Men, X-Men 2, Fantastic Four, Elektra, The Punisher
As you see most of Dc's are batman flicks, they need to be more creative.
I like Marvel best
