Watched the Avengers, liked it, but it did show how week the standalone Captain America film was, I'd completely forgotten all that stuff about the tessaract etc. Hate the new Captain America costume too. Had to google to find the shawarma avengers ending on youtube. For some reason only the US gets that post credit sequence.
ITV2 showed the Incredible Hulk on Saturday, which was good, as it got the Ang Lee version out of my mind in time for this.
I wouldn't bother watching it in 3D, it added nothing to the movie.
