It honestly depends how they're going to market the film like several of you had said. The studio needs to do a fine job though, because a lot of people who aren't familiar with the Marvel superhero, Thor, other characters like Spider-Man and X-Men pop up in their mind. Idk, my predictions for this summer's super hero movies is that Captain America or Green Lantern first, then Thor, then X-Men First Class. But who knows, it's possible that Thor becomes a huge hit, just as long as Critics give positive feed, along with the pubic, and excellent marketing, and just maybe, it can be this years "Iron Man."
