Saw this last night, liked it quite a bit. Directed by the same guy who did Moon and has some similar themes. Been reading reviews that say the ending was tacked on but I actually kind of liked it. Definitely worth seeing if you like sci-fi thrillers. Good acting as well, loved Vera Farmiga especially.

the only thing i don't like about this movie (and i haven't seen it yet) is Jake and his muppet eyebrows. maybe he's ok in it, i'll have to see.
