Probably the best movie I've seen in a decade or better. Along the lines of dances with wolves, Lonesome dove, and the like. Wonderfully done, very few special effects, the bear scene was CGI, but damn you could never tell it. The whole movie was awesome IMO.
The story line is fucked, as it doesn't truly follow Hugh Glass's story of the ordeal he survived, so it loosely based on the true story and incorporated some story's of other events during the frontier era. If you were a history nerd about the frontier era (as I was and somewhat still am), you should fully enjoy the movie.
Funny, I took my wife to see it, about half way into it she tells me "there is no way anyone could survive something like that" so I told her "you do realize its loosely based on a true story". Of course she did not believe me until I made her read a wiki page about it. She asks me, how do you know all this stuff, so I pulled out my dads Time Life series that covers the entire beginning of America that I have been reading/referencing since I was like 6-7 yrs old. lol she called me a nerd...first time for everything I guess.
Go see it, its worth it.
