Unless you've been in a sensory deprivation chamber for the past month, you've heard there's some horror movie named "Paranormal Activity" ruling the box office. It was made for, like, $10 and has grossed $1 billion or something.
"Jennifer's Body" is the perfect movie at the perfect time for Megan Fox. She has become a huge star without playing a single lead role or having to really act at all (something even she admits). She has built a career on rocking red carpets and lending her eye candy to action movies.
Writer/director Mike Judge captures the hilarity of the workplace as well as anyone. His "Office Space" (an American classic, in my opinion) and "Idiocracy" both flopped in their theatrical runs but have become DVD hits.
