Look, maybe I’m biased. The Avengers movie by Joss Whedon… well, Captain America has always been my favorite hero, with Iron Man not terribly far behind. But the original movie (I haven’t actually seen Ultron yet) is to me about the perfect superhero movie. I mean, we start with a disparate group of somewhat feuding heroes, sparring over issues, fighting each other (Thor vs. Hulk?, Iron Man vs. Thor?) then forming a solid team making an incredible force. Witty dialog (very comic book), and a great implementation of the Hulk, a complicated at best hero.
An epic battle at the end, with a solid ending. Great action. Tell me there’s a better one!
