I saw Horrible Bosses the other week, and that was fantastic. It rivaled the Hangover in my mind. Also, Rubber was the most ingenously rediculous movie I've seen in a long time. If you haven't seen it, it's on the Netflix instant watch under foreign or comedy. (and no, it's not about condoms. its about a car tire)
I've been meaning to get around to watching Rubber since I first saw a trailer for it about a year ago. Also under the same vein of gritty ridiculous movies, I recently had a chance to see the masterfully disastrous 'Hobo with a Shotgun.' This movie is the epitome of grindhouse cinema, meaning it's terrible, but for all the right reasons.
I have been meaning to watch this for months now. My friend keeps forgetting to get it to me.
