I must say, I'm not what you would call a liberal. I'm a Democrat, but I don't consider myself one of those "limousine liberal" -- re: rich, white middle-class people who have never endured poverty in their live, and yet somehow can "feel" for those currentlys uffering. Yeah, right!
All that side, this is a wickedly funny movie and completely unpredictable. I love the intense scenes with the cop and when the liberals start to contemplate rather they should kill or not kill their dinner "guests." it's just great stuff!
Imagine, all these "tolerant" liberals sitting around judging people on what they say and starting to actually LIKE killing. Pretty soon they're killing because of the power of killing, not because they want to "rid the world of evil" -- which, ironically, they've become, since they're knocking off everyone and their mom, including the cop, who is just doing her job.
As the saying goes, "I can't tolerate intolerable people!"
And stay for the ending. It's a KILLER! Ron Perlman is GREAT.
