An innocent Christian girl discovers her vagina has teeth of its own. On its gleaming white surface, Teeth looks like another gross-out horror comedy. Judging from the just-released trailer, it's definitely over the top. But critics are already praising its exploration of female sexual empowerment through mutation.

When Teeth premiered at Sundance, Cinematical wrote:

At first Dawn is freaked out. Then she begins to realize that her difference empowers her. She no longer has to live in fear of her stepbrother's sexual attraction to her, or worry about date rape or random perverts; her vagina, rather than her greatest weakness, is her greatest weapon.

Obviously it's pretty lame if your vagina has to be jacked up to become empowering. But other critics saw Teeth as a metaphor for sexual ignorance and fear of sexuality. Whatever your take on it, Teeth could be the next Fido when it hits theaters early next year.
