Definitely worth the watch, as this film festival dark comedy is quite original in its outlook, with heavily feminist leanings from beginning to end. What I found most ironic is that her teeth almost become a superpower used for the betterment of the world -- just surely not the kind of powers seen on a CW show. I enjoyed watching the scenarios play out and how there's a modicum of control for the teeth. Very good.
There are actually some entertaining, if not goofy, symbolic flourishes (I think the smoke stacks were the most restrained), but the final point of the movie doesn't make it all the way to a balanced perspective. Men are almost uniformly awful here, which means continuous mutual pleasure is out of the question. Sophomoric vengeance rules the day, and 'Teeth' could have stood to think with its brain over its 'organs'.
