Never mind that the film is scripted by Oscar-winning writer Diablo Cody. According to this trailer, the dialogue plays a distant second fiddle to the physical charms of Megan Fox

I wonder how long it'll be before a trailer opens with: "In a world where Megan Fox gets naked …" It might not represent the whole film, but it would make some studio bosses ever so happy.

Just imagine: "In a world where Megan Fox gets naked almost constantly … Where even the loosest clothes prove strangely restrictive … And sprinkler systems have a habit of going off at the most inappropriate times …"

"… And swimming in the nude is not only an option … it's compulsory."

Or, as the trailer-man would pronounce it, "CUMPULSEORORERRY", because inserting fewer than five extra syllables would be a waste of breath. And so it would go on, perhaps promising, "One man had to choose whether to love, or whether to die", or something.

There do seem to be some other things happening in the trailer for Jennifer's Body, other than the presence of the lovely – and terribly popular – Ms Fox. It would appear to be a story about the most attractive and popular girl in school, the kind that – say the ominous words on screen – all the girls want to be friends with and all the boys would die for. That girl is Fox.

These words are to be taken literally because she also, as coincidence would have it, eats teenage boys. And girls, when she's feeling that way inclined. We're not entirely sure why, from the trailer. But just know that to be the case. Megan Fox: she's a man-eater. Official.

Being a teenager now means dicing with death on a daily basis. It's a world fraught with danger. In the heyday of John Hughes – may he rest in peace – it was more a case of debating whether going out with someone meant compromising your social standing.

Whereas now the question is, invariably: "Will you go out with this person even if doing so is likely to cause you to die a bloody and painful death on account of their being supernatural?"

If you can get through your teenage years now without falling in love with – and/or becoming prey to – a vampire, troll, werewolf, warlock, demon or in fact whatever it is that can do this without hurting,

then you're frankly not trying hard enough.

What with all the promise of spooky love-tangle and bloody murder on display, it's a surprise to learn that this is the latest from Diablo Cody. If there's much whip-crack dialogue of the quality of Juno in Jennifer's Body, it's difficult to see where they're keeping it.

Certainly, this trailer seems to be promising less talk, more action. More lip-licking, teen-chomping, hot-tongue action. And explosions, of course.

That's Amanda Seyfried, who plays Jennifer's best friend, here demonstrating the "cool guys don't look at explosions" rule, as well as that her world-saving activities will, in no way, interfere with Megan Fox wearing as little as possible, to a rocking soundtrack.

Whoever this trailer has been marketed towards, it's clearly with the key points of:

1) Hot Fox

2) Horror

3) To a mainly emo soundtrack you'll love!

Is that all there is to Jennifer's Body? Sometimes people end up missing out on some very clever films just because they've been branded "genre teen flicks". Or perhaps not. Maybe this is just points one, two and three, on a loop. In which case: great trailer!

Sigh.
