Well, since we're doing this...

X1: At the time, I was impressed. Disliked the "leather" look, but it was what it was.
X2: It was good. Nothing to write home about.
X3: Hated it.
Origins: Best Sabretooth so far. Best Deadpool. Right up to the end. WTF were they thinking?
The Wolverine: Mediocre at best. The potential to unleash the savage Wolverine fell flat - like when the ninjas all speared him and Wolverine fell flat in the snow.
First Class: So. Much. Hatred.
DoFP: Good, for what it was. Almost a really good movie. Best direction up to this point.
Apocalypse: Really good, except for all the things I hated and nitpicked.

The problem is - FOX is now trying to tie these universes together, but they've changed the cast of main characters so many times by different actors, that it's nothing but a cluster fubar.
