They didn't do only a below average movie… They also runied Dead Pool!
X-Men movies in chronological order:
Best X-Men movie to date. Do not listen to the comic fanboys here. Excellent screenplay, story and music. This is Wolverine's origin story and they have done an excellent job. I wish there was an origin story for Cyclops too.
Wolverine isn't Bad, but it's not as good as it could've been.
Like the 3 other X-Men movies quite good an enjoyable.
