Super Hero movie-watchers have definitely been trained to stay through the credits in case there is an extra scene at the end. My wife and I sat through the credits of this one, along with a large chunk of the audience, and when the credits ended without any extra scene there were quite a few disappointed "Awwww"s from the crowd. Anyway, this movie was lots of fun and, unlike XO:Wolverine, it was never boring. I still want to see an X4 that follows up on the events of The Last Stand, but if they only make sequels to First Class with this new cast, I'll be happy. Of course, the disappointing box office is calling that possibility into question.
