Went out to see this movie this morning, and I'm a bit torn. As far as story, acting, and action goes, it was a lot of fun. I had absolutely no problem with the actors who played their characters, and I think they all did marvelously. There was even a cameo of Hugh Jackman as Wolverine, which was spot on. A plausible story, even if it didn't fit into cannon X-Men lore. Some parts did, some characters did not, but in the end, it all came together quite well.
My big issue was with the characters. Beast, Professor X, Moira McTaggart, and Magneto, as well as Sebastian Shaw, Azazel, and Shinobi Shaw, I get. Banshee COULD fit in there, even though he was introduced in a different way in the comics. Darwin was a great add-in, though he was actually the 2nd class, in between Cyclop's class and Wolverine's class, in a group that was put together that were all killed by the living island. Funny enough, the 3rd Summers brother was also in that class, and yet neither Scott or Alex ever knew of him. Weird, I know. Mystique was put in there rather nicely, and while I confess to not knowing her origins, I think it went rather well. Angel, I've never even seen in the comics, but that doesn't mean anything. Alex Summers, however, was the anomaly that messed it all up. He's Scott's younger brother, yet he appears in this movie, 30 years before the first X-Men movie, give or take. The FIRST CLASS to Xavier's School for Gifted Students was Scott "Cyclops" Summers, Bobby "Iceman" Drake, Hank "Beast" McCoy, Jean "Marvel Girl" Grey, and Warren "Angel" Worthington. I wish that was how they had begun the series, and how they had revisited this one. Still, I did enjoy how things went.
If you haven't seen it yet, you do need to, it's worth the view.
