My wife and I went yesterday, it was enjoyable for the most part. I'm in no way a Marvel/Wolverine aficionado as far as what was true to the origin story and what wasn't, but there were a few instances that stank of FOX meddling.
When I first saw the Scott Summers was in this I wasn't sure how they were going the explain away them not recognizing each other in X1, but they handled that well enongh. I liked Liev Schreiber's take on Victor, but boy does it make Sabertooth in X1 look even more lame. I really liked the opening credit sequence showing the passage time through all the wars they were involved in. I wish we word have gotten a bit more of that. I did notice Daniel Negreanu right off which was fun.
For me the most groan worthy scene was the Jar Jar-esque fumbling in the old timers bathroom and certain scenes of boiler plate dialogue from various characters that you've heard 1000 times before and deliver better.
As for the ending I saw, it was the Stryker on the road scene.
Oh, and I got to see the TF2 trailer again - it made me want to touch Megan Fox's butt... again. Do you think she was wearing panties? Me neither.
