2. It's awesome, from beginning to end - If you go in expecting a horror movie, you may be disappointed. It's much smarter than that. Instead, it flips the horror genre on it's ass, recognizing all the cliche's and gives the audience a satisfying reason behind these cliche's. Totally awesome.
3. Casting Problems - I would say that my only problem with the film lies with the casting, but since the film sort of answers why these "actors/characters" were cast, it's hard to fault it. I loved the casting of Dollhouse alums, Fran Kranz and Amy Acker. Plus, Richard Jenkins and Bradley Whitford stole the movie. However, I do think they could have found more charismatic actors for the rest of the group.
