Loved this film, possibly because I haven't read the book (as Joe Leydon suggests). Beautifully shot (Fimognari), designed (Sullivan), and edited (Flanigan). Flanigan really gets to show off his honed director chops with this material. Carla Gugino, Bruce Greenwood, and Henry Thomas are all great - that is, the men are great creeps.
Very well-made film, but not nearly as fun as the trailer and reviews led me to expect. I guess if you think Christmas ties and sweaters in and of themselves is hilarious... It's not really trying to be scary either. It's kind of Christmas-torture-soft-porn. I guess it might be fun during Xmas season as an antidote to seasonal schmaltz.
A virus that makes people lose their inhibitions spreads through a highrise corporate office building just as Steve Yeun, having been set up by a vicious co-worker is fired. The mayhem that ensues as they are all trapped in the building together, under quarantine is gleefully dark. As social commentary goes, its on the light side, but Yeun is so perfect here, equal parts vulnerable, sensitive, corrupt, and ruthless. Samara Weaving is fun as the woman fighting her foreclosure, wielding a nail gun and sneer.
