X-Men: The Last Stand
The plot: A cure is found for mutants but it doesn't go down well. Magneto begins to raise an army while Xavier tries to prevent all out war.The good: Captain Picard and Gandalf in the first minute of the movie - what more could you ask for? Some shockers too.
The bad: There isn't really anything wrong with this movie. But then it's not the most amazing movie ever either.
Conclusion: It's a fun movie, if you like X-Men then you will certainly enjoy this. As comic book franchise movies go, this is a very good one.
