When you consider that they had to go from the standpoint of introducing a large number of characters, their powers, and make it seem realistic, to people who had no idea what X-Men are (they can't aim for people who know what's going on, or the movie would have flopped) they did an incredible job! When I went, the theater was packed, and it was one of the first movies I've seen in a long time where people laughed throughout and actually clapped at the end.
