I'll see it, but I really don't think they're going to make the Avengers work. I don't know how you load that many characters into one movie. They did so well with most of the lead ins (except the Hulk screw up), so I'll give it a chance.
I'm sure I've said it on here a few times, but Batman is clearly the highlight of the year for me. Those first two movies are the perfect example of how "superhero" movies (yeah, he's not really a superhero) should be done.
