I was blown away by it, it was awesome..it was worth the wait to get into the IMAX to watch it in 3D.
If you haven't seen the Iron Man, Capt America or Thor movies....yeah, it might help to watch those...the second version of the Hulk is the best one, but like tRdoc said, doesn't really fall into place like the others.
All in all, its a great flick...and make sure to sit through ALL the credits....when it comes to the Marvel movies, always sit through the credits.
