I drove to Houston last night to see the screening, and I'm going again in my hometown (Austin) tomorrow night! The movie is hilarious, and you should definitely give it a shot, as long as you don't mind profanity. Andrew Bowen was at last night's screening for a Q&A, and he said he thought the movie beat out South Park in the f-bomb total.
Profanity aside, the movie features some solid performances by Bowen and Felicia Day, as well as the one and only Doug Jones in yet another great creature role. I was a little disappointed that Jason Mewes and Robert Picardo, who were featured in the trailer, didn't play a bigger part in the movie, but they got laughs every time they were on screen. I can't wait to see what first time writer/director Paul Seetachitt does in his next movie!
