WARNING: SPOILERS!
Saw it. Didn't really like it that much. Didn't really care that it was a homosexual relationship. Did care that there really wasn't a whole lot of relationship. It seemed like the hetero equivalent of a series of one night stands between two cheating spouses. It seemed to be sorely lacking emotional development between the main characters in the first half of the film. It wasn't until the last third of the movie or so that I felt that there really was something between them, and really more from Heath Ledger's side. Jake didn't really convey his emotional need for Ledger's character that well. I think it was a beautiful film aesthetically, with several subtle but excellent performances (Michelle Williams is worth mentioning). Heath Ledger's portrayal of a tortured soul is especially good, a ranchhand who can't come to grips with his past nor accept himself for what he is in the present and is destined to live an unhappy life bound to societal norms. But because I didn't really buy into the relationship that was at the core of the movie, I didn't really like the movie that much. It didn't move me.
BTW, Anne Hathaway once again tries to put her Disney past behind her in this film. Anna Faris also has a humorous bit part in the film.
One question though. Is it just Ennis' paranoia that causes him to see Jack getting beaten to death by an angry mob (as Jack's wife is explaining his death due to more mundane circumstances)? Or is it really what happened, just "glossed over" by the wife? I'm assuming that if Jack had in fact been killed by an angry mob, his wife could have cared less about fulfilling his last wishes.
