The film opens with Needy Lesnicky (Amanda Seyfried, forced to hide her beauty behind some glasses) holed up in a mental institution, declaring, "Hell is a teenage girl." This statement illuminates the very fine line every adolescent girl walks while waiting in the limbo between childhood and adulthood. It can feel as though the whole world is against you, yet your small, high-school social life (or lack thereof) is your whole world at that fragile stage. Needy is just another victim of female adolescence, but what remains unclear at first is how she ended up institutionalized.

The film then rewinds to a fateful night in the small town of Devil's Kettle. Needy and her BFF Jennifer Check (Megan Fox) go to see the band Low Shoulder play at their rural town's only "club," and end up talking to Nikolai (Adam Brody), Low Shoulder's lead singer. Needy overhears Nikolai discussing whether Jennifer is a virgin with his bandmates and fatefully confirms that Jennifer is indeed as pure as the driven snow. When a horrific fire breaks out and burns the bar to the ground, Nikolai offers refuge to a shocked Jennifer in Low Shoulder's van.

What happens after this point is unclear, but in the middle of the night, a blood-covered Jennifer appears in Needy's house, her movements and eyes transformed to an animal-like state. Needy, completely petrified by Jennifer, is now forced to live among peers and adults who all seem oblivious to the crisis that unfolds in Devil's Kettle when people start dying. Why is it that parents never seem available to help in teen horror films? Although there is no huge twist in the film, the revelation of what really did happen to Jennifer's body will satisfy the audience well enough.

Director Karyn Kusama provides the film with gorgeous visuals that surpass many teen-oriented films being produced today. Kusama brings out the best in Fox and Seyfried, who both fit perfectly into the archetypical roles they've been given. Fox especially excels as the devious Jennifer, delivering her Diablo-isms with the sprightliness that Transformers does not allow her.

In comparison with the writer's Oscar-winning Juno, Jennifer's Body has no lack of bizarre quips and slang. Cody's dialogue can make you either laugh or cringe. Look for the terms "lesbi-gay," "shutties," (shut up) and "Hello Titty" to make it into the pop culture lexicon. However, Cody cannot seem to steer clear of Phuket, Thailand jokes, one of which appeared in Juno; at one point, Jennifer embarrasses Needy and her BF Chip - "It smells like Thai food in here. Have you two been phuking?" In spite of this misstep, there are laughs to be had and even a tear or two to be shed in Cody's creation.

Jennifer's Body blends comedy and horror into a delicious fruit smoothie of sorts, punctuated with the pop dialogue that has now become Diablo Cody's trademark. Her films seem to be thoroughly enjoyable among a specific group -- college-age kids with a background in suburbia and alt-rock. I'll admit that I fit into that demographic, but I was still pleasantly surprised by the fun of Jennifer's Body, which will remain a love letter to anyone who's ever been a teen girl living in her own cruel world.
