It's a movie that's not nearly as hyped as Age of Ultron and maybe that's a good thing. Besides, why does Disney need hype at this point? They have a fucking Star Wars movie coming out in a month. I think they're worried about frying our brains with pure awesome at this point. Having fried my brain enough by sitting through shitty Batman movies in the 90s, I'm okay with letting some hype build for this one.
Will this movie be as big as the original Avengers movie? Probably not. Will it top Star Wars? Definitely not. Will it still be awesome? After seeing this trailer, I'm going to go off on a limb and say fuck yes!
