While I thought the original was a tad better, the second X-Men film was really good as well. Pretty much all the mutants from the original return, along with many new faces.
Though some of the new cast-members are rookies at the academy and the older X-MEN at times feel like babysitters.
I didn’t really think Lady Deathstrike or that army dude were that great of villains though. I do like the stuff about Wolverine’s past however.
