As a movie trilogy, decent. As a comic-turned-movie trilogy, completely off.

Rating: 4/10 (26 May 2006)

First of all, this particular installment is best viewed if you go into it with NO EXPECTATIONS. The storyline is established enough to give the characters something to work off on, but it is weakly developed and supported.
Angel's role is limited in scenes (something that was falsely advertised as him having a bigger role in this movie). Jean Grey's Phoenix entity is explained in a way that doesn't agree with the comic's explanation (and she's barely referred to as "Phoenix").
Effects and action scenes were fantastic, but there isn't depth to it.
I think this movie is best viewed as separate from the comic world. What you think you know about the X-men world doesn't get honored or acknowledged much in this movie.
I liked it for what it was, but I hated it for what it wasn't.
