3. Batman Vs. Superman
This is an unfair one. Marvel simply can't compete. There's no match-up in their catalog that amounts to the awesomeness that is Batman Vs. Superman. DC owns the rights to arguably the two most well known superheroes and they have a wealth of material to draw from when it comes to these two characters acting as foes. One is a mere man fighting for his own version of justice with little sympathy for people that get in his way. The other is practically a God fighting for truth and the American way. They are polar opposite characters and yet they are worthy opponents. These two colliding is like watching Greek Gods fight for their place on Mount Olympus. Sure, Marvel has shown us Thor and Captain America fighting and it was pretty cool, but those characters don't come with near the same baggage as the Dark Knight and the Man of Steel. It's a team up/fight we will always remember when it comes to the big screen.
