Jennifer's Body stars Megan Fox (Transformers), who reprises her "hot babe" style role and Amanda Seyfried (Mamma Mia) who is trying to play a convincing "ugly duckling".
Basic plotline - Jennifer thrives on the flesh of boys. If she doesn't get flesh / blood often enough she begins to lose her looks - getting paler and more "washed out" over time. The fresh blood keeps her looking young and attractive
I could go into more detail about the dynamic between the two leading female actors. (The lesbian undertones are quite interesting... )
I could try to justify the script's weaknesses
I could even try to convince you that it was worth going to see, but who am I kidding?
Jennifer's Body will be available on DVD, BluRay and cable TV. Wait until it is.
