Saw it last night. It was a great movie. Depressing as hell though. I'm all for movies that cross the line and go against the typical movie formula and are just plain fucked up but...
*spoiler*
I liked the twist of the hunter getting shot in the hotel. Didn't see it coming. But when he tracks down his wife and they have that talk about him having to kill her after she comes back from her mom's funeral and then it just shows him walking out of the house and checking his boots for blood. I was just thinking... "really? Ugh... 
. Just too depressing. Probably the only time that a movie has ever genuinely depressed me."
As far as a movie though, it was pretty awesome.
