Ultimate Avengers, with...several voices of various people. This is one movie I would not have gone out of my way to see, or perhaps a better way of phrasing that is I only watched it out of obligation. It wasn't unpleasant to watch; it was actually a decent animated movie, it's plot wasn't entirely cohesive or deep in any way, but it didn't need to be. I was never really a fan of the Avengers as a comic nor the Ultimate spinoffs, so that probably colors a large portion of my opinion. That said, if you like the Avengers and that kind of traditional, superhero comic, this movie is actually probably quite enjoyable.
