Saw The Avengers over the weekend. I was a little worried it wouldn’t live up to the massive amount of hype, but happily it did.
BEST. MOVIE. EVER.
For anyone who hasn’t been following what Marvel did to build up to The Avengers there’s a great summary of the Marvel Cinematic Universe on Wikipedia. This kind of cross-pollination of characters across multiple storylines to place them in the same universe hadn’t been done in cinema before, despite being very common in SF and fantasy. (That I’m aware of at least. Correct me in the comments!)
