“Jennifer’s Body” a witty, surreal teen comedy

Amanda Seyfried weathers flesh-eating demons, whiny indie bands and poof sleeves in "Jennifer's Body."

I knew it. I knew it. I knew that if I hoped and prayed and wished and waited a long, long time that the Bizarro Alternate World would take over and the unthinkable would happen. And in “Jennifer’s Body,” the unthinkable has become reality: The brunette’s dicing up male hearts like room-temperature butter, and her mousy blonde friend — who wears tortoise-shell glasses! — is nothing but a mopey, fraidy-cat sidekick.

(Sigh.)

It turns out this is not Bizzaro Alternate World so much as just the warped plot of the Diablo Cody-penned wittier-than-thou “Jennifer’s Body,” a pointless but way fun horror comedy that lampoons teen movie cliches with wicked glee. And since this is, you know, Diablo Cody, all the fun is wrapped up in dialogue so sharp and self-conciously urbane that you have shredded murder victims described as “lasagna with teeth” and an indie band frontman (Adam Brody) who yearns to “reach out to fans in the shitty areas, too.”  

Yep, “Jennifer’s Body” is that kind of movie, another hip reinvention of the teen horror movie that ends up completely farfetched but also completely enjoyable. Part of that trashy fun stems from Megan Fox’s rather impressive performance as Jennifer Check, the resident hottie at Devil’s Kettle High School who spends her post-cheer practice time consuming male flesh. (She’s not killing people, you understand; she’s “killing boys.” There’s a difference.) There’s Brilliant Subversion No. 2 — a girl who’s not the victim, who is, in fact, making mincemeat out of boys? Love it. Standing petrified on the sidelines is Anita “Needy” Lesnicky (the insanely talented Amanda Seyfried), who suspects her more socially desirable B.F.F. — “sandbox love never dies” Needy offers up as reasoning for their unlikely friendship — is a killer. Too bad Needy can’t get her sensitive, Strokes haircut-sporting boyfriend Chip (Johnny Simmons) to believe her. But she has to try real hard because if not The Big Dance will become (he he) an “all-you-can-eat buffet.”

That’s what I love most about “Jennifer’s Body,” lines like that. These words bear no resemblance to the way people actually talk, though if they do it’s probably because everybody saw “Juno,” figured it was the new “Clueless” and started a flip pad of jargon. (Come to think of it, that isn’t a half-bad idea, starting a log of Diablo Cody-isms. She’s so hot these days.) There are other killers so funny it’s nearly impossible to laugh at them. Needy and Jennifer’s pet names for each other? Monastat and Vagisil. Jennifer is “actually evil, not high-school evil.” When Chip’s mom begs him to carry pepper spray to the dance, he responds: “I can take care of myself. I’ve been using the Bowflex.” And there’s a bit about Thai food and sex that might cause public consumption of pad Thai to go up or down depending.

This whimsical absurdism bleeds (pardon the pun) into much of “Jennifer’s Body,” which means there’s not much substance — unless you count the characters. Fox does more than what’s expected of her — she proved she had comedic chops in “How to Lose Friends and Alienate People,” but, really, who saw this coming? — and has a lot of fun with Jennifer. Her delivery’s just right, though it’s doubtful any man in attendance will notice. With the way Fox fills out her teeny heart hoodies, ushers should have buckets handy to catch the drool. But enough about Fox. Why use too many words for her when there’s a better, meatier part played by a better actress with more range? Given her own fair looks, it’s shocking to see Amanda Seyfried plain-Jane it up as Needy, but she looks every inch the meek friend. There’s a sadness to Needy that Seyfried’s not afraid to explore, and later a looming darkness that’s unnerving, not the least bit cutsey. This is why Seyfried will become a household name — she’s got such talent you can’t help but like her in anything.

Jennifer may be the body, see, but Needy’s the soul. And hey, someone’s got to do the real heavy lifting while Megan Fox makes sexy.
