This is a horror comedy in which Jennifer, a high-school vamp (Megan Fox), turns out to be quite literally a maneater.

The best line comes when her shocked best friend (Amanda Seyfried) gasps: 'You're killing people?' And Jennifer replies: 'No, I'm killing boys.'

It's meant to be campy fun, a hipper, more gruesome version of Twilight, with softcore girl-on-girl kissing and 'cool' shots of male teenagers being devoured by the hot-looking chick from the Transformers movies.megan fox latest hairstyles
