The BLUF: A great popcorn movie. Nothing earth-shattering is happening here, but it's just fun. As long as the fanboys can get over the differences between comic and movie and the continuity issues between X-Men movies and this one, get over the beginning of the movie being set in the Canadian Northern Territories in 1845 (at least 30 years before that could have happened), get over the use of M4 carbines in a Vietnam War-era sequence, get over the use of HMMWVs in the lase-70s/early-80s (before the fielding of such vehicles), and you've got a fun movie. It's a high-octane, full-frontal assault of action and snikting.
My only complaint, cause really, it was easy to get over all the things I mentioned above, is what they did to Deadpool. Such a good character wasted that way. Hurm. Anyway, if you like these kinds of movies, you'll like Wolverine: Origins. It's not the best comic-book-based movie, but it's far from being the worst.
