What do you get when you combine a bunch of Marvel and DC characters into a 45-minute animated fan-made movie? Well, you get a little bit of everything, as well as a film that's ballsy enough to call itself The Greatest Fan Film of All Time. While it definitely starts out a little slow and gimmicky (though the superhero party did crack me up -- especially the Rogue and Ninja Turtle gags), this puppy does begin to get interesting around the 15-minute mark when evil villains like Joker and Scarecrow plot to turn all the good superheroes against each other -- which, eventually, turns to all out destruction as superheroes battle other superheroes in one big bloody mess of awesomeness. (Oh, and even Comic Book Guy from The Simpsons makes an appearance. Seriously everyone is in this thing!)
