Went to the midnight screening on Friday morning. The thirty minutes of previews was fairly obnoxious...but once the movie was started it was pure adrenaline for me.
I won't post any spoilers, but let's just say that it was the Hulk's coming out party. Finally he gets a film role worthy of the epic character.
I'm a big fan of Joss Whedon--obviously there's a lot to say about how great Firefly and Serenity are. He's also the author of my all-time favorite comic, Astonishing X-Men.
Can't wait until Avengers 2. Only recommendation is that you stick around through the credits. Like usual, there is a post-film teaser, but there is a bonus scene after all of the credits.
