Here're the good bits that you can't totally divine from the trailer, but head on over to WeAreMovieGeeks for the whole write-up...
SPOILER WARNING: You have been warned!
Fast forward to 1970-something Viet Nam. Logan and his brother Victor (aka Sabretooth) are soldiers and Victor has become an irrational bully who has no problem killing anyone that gets in his way. This leads to both of them being locked up in the brig for a very long time. Enter a higher up military officer (Stryker) who offers to get them out of there if they agree to join his special ops team. This elite team is made up of other mutants, all with various different, really cool “powers.” Mission after mission goes by, with Victor really taking a liking to the violence and developing an appetite for killing. Logan, on the other hand, draws the line at being ordered to kill innocent people and decides to walk away. Off he goes to live a quiet life in the Canadian wilderness with his girlfriend/wife/whoever
Cut to various former members of the special ops team being killed. No reason is apparent. The former leader of the group (Stryker) finds Logan in his now lumberjack career and tells him about this. Logan says thanks for the warning but I can take care of myself. As he returns to his work, he senses something is not right and then notices bloody claw marks on a tree. He runs to find his girlfriend/wife/whoever lying dead with gashes across her throat. Victor has killed her. Now its personal and Logan flies into a rage. He finds Victor and a battle ensues. But they basically have the same “powers” so it’s impossible for one to beat the other. Victor flees and Logan agrees to let Stryker help him become more powerful, and therefore able to go kill Victor. Cut to the “lab” scene from the trailer, new steel blades ready to do some serious damage. I don’t want to give it away, but one of my favorite parts of the movie is when we find out where the name “Wolverine” comes from… oooh I just got goosebumps thinking about it… haha. HUGE SPOILER: “the crazy mad scientist, Stryker, is kidnapping them all (mutants) and keeping them prisoners because he is takin their DNA to make a Super Mutant…one guy with ALL the powers... IT’S RYAN REYNOLD’S CHARACTER, Wade Wilson / Deadpool...its so creepy when you see him at the end!!”
The reviewer ends by assuring us that there are great fight scenes and a ton of "holy @#%&!!" moments -- declaring that fans will cheer. While some of this could be figured out from the trailers and clips we have seen, it is odd that the spoiler didn't mention more about the Silver Fox. In the comics she is not actually killed and joins the Weapon X program. Also, the war in Viet Nam was pretty much over by 72, but that is a minor history error that may not have been relayed in the movie at all. Lastly, and most bothersome is that he teases stuff like the origin of Wolverine's name, and that there will be some end credit stuff, but he doesn't tell us what it is. Why wouldn't he spoil THAT since he's spoiling everything else? For my part, I'm a bit skeptical about the validity of this review.
