‘Jennifers Body’ appears to be a dark comedy.
There are humorous parts that are related to some sort for sexual innuendo or blatant sexual act (such as the charming description of Jennifer, played by Megan fox, who had to sit on a bag of frozen vegetables after losing her ‘backdoor virginity.’)
But there are good suspenseful horror moments, there were a lot of scenes with ‘cheap scares’, the typical “I know someone is going to jump out now, I’m just waiting for it” scare.
Yet, the blood and gore was convincing, and we have to say that the scene where Jennifer appears in her best friends house covered in blood, giving a demonic blood filled smile and spewing out black goo was pretty good horror.
You gotta love those guys who make the Trailers to these sort of films they do a great job of generating interest!
Nerdy, reserved bookworm Needy and arrogant, conceited cheerleader Jennifer are best friends, though they share little in common.
They share even less in common when Jennifer mysteriously gains an appetite for human blood after a disastrous fire at a local bar.
As Needy’s male classmates are steadily killed off in gruesome attacks, the young girl must uncover the truth behind her friend’s transformation and find a way to stop the bloodthirsty rampage before it reaches her own boyfriend Chip.
