Megan Fox plays a nasty, evil carnivore looking to spill blood and gore as she feasts on human entrails. But all that's just metaphorical as the movie focuses on her BFF, "Needy", and all the fears and insecurities of a teenage girl growing up.
Best friends are forever, right? But what if your best friend turned into a monster overnight? What if your best friend starts behaving in ways your mother told you never to? What if she makes it a point to steal your boyfriend and other boys that show an interest in you?
For the boys, there's always the fear that if an attractive girl shows interest in you, it must be too good to be true. And many times, it is. At the back of your mind, you know that all she wants is a piece of you -- and in Jennifer's case, lots of pieces. It's the fear of the male black widow spider; the male preying mantis; egged on by the need to fertilize, yet helpless to change his fate.
And remember mother's advice about never getting into a strange van with strange boys? Yep, that's what kicks off this gruesome morality play in the first place. Jennifer is never quite the same after that night.
"Jennifer's Body" is horror in the category of teenager vs monster with superpowers. More thrill than chill, really. What's interesting is that the fears are both common and real, though we don't usually think of them as particularly monstrous. They are fears we eventually outgrow, but to a teenager experiencing them, it sometimes does feel like something's eating away at one's insides. Her name, we know now, is Jennifer.
