Teeth.
I have always been a Big Fan of horror movies, especially "good" ones. I use the term "good" loosely though, because I usually like the bad ones too.
So when I hear that there's a movie about a teenage girl with teeth in her vagina, I can only imagine that it blows past the "good" rating right on to "outstanding". The movie is aptly named Teeth, and it truly is outstanding.
Sure it's a bit uneven sometimes, but it's a hell of a second directorial effort by Mitchell Lichtenstein, who interestingly is Roy Lichtenstein's son. Stellar performances by Brooklynite Jess Weixler as the "heroine" and especially John Hensley as the asshole brother make this pitch-black comedy GoodTimes to watch.
As in-your-face as a castrating, voracious vagina is, the movie is packed with loads of subtlety. For example, Weixler is hot, but she's also weird looking. Her Austin home is straight out of Anywhere, USA — save for the nuclear cooling towers that loom behind it. There is gratuitous male nudity, not female, and Weixler's teenage character and her victims are all prudish abstinence-preaching Neo-Christians.
Most importantly, I wish my penis had an extra something. Like maybe an extra set of hands, so I could have it answer my cell and take calls, or play Xbox with me and such.
