AOTC refers to Star Wars Episode II: Attack of the Clones. It's one of the worst movies in human history. X-Men: Last Stand was close to that level of futility.
For once, I actually agree with Barend. They should have introduced Gambit in this movie.
The problem I had is that usually introducing a new character means that they will have significant role in the movie. For example, Wolverine played a big role in the first X-men. Night Crawler was introduced in the second X-Men movie, and he was critical in saving several characters as well as getting into Cerebro room. ArchAngel didn't do anything remotely important, aside from saving his dad.
So yeah....bad movie.
