Avengers really is a truly superb film, I've been a comic book reader since I was a wee youngling, and this film lived up to what the Avengers are all about, everything was fantastic.
Although I must say, when I read the reviews in Empire magazine, they said it would basically be from the point of view of Captain America, as he was the most relatable character, as being from the 40s, he was the most out of place.
But I think they were wrong, I think that Hawkeye and Black Widow led the film, and I was paying more attention to them, those two stole the show for me.
