As a casual Marvel fan, I was disappointed.

Rating: 2/10 (11 November 2013)

It's like they didn't watched the movie before releasing it.
There's no explanation for Viper's motives, and why did she change her skin in the middle of a fight scene, which didn't made her stronger at all. It made no sense.
They should be a lot clearer in let us know the time line. After searching Google, I found out this is after the third movie, X-Men: Last Stand. Wolverine has a lot of dreams/hallucinations about Jean. They should have started the movie with a scene right after the ending of Last Stand, so the audience would get a clearer picture of what was going on. Not just a scene where he wakes up in the woods after ?? years after a war.
Also when Wolverine's powers was disabled, he took a lot of bullets and jumped from a high building, but he just kept on running like it didn't hurt him at all.
Plot holes and an overall boring move makes me give this movie a 2/10
