I just watched the trailer for this film over at Apple.

I know it's not to be taken seriously, but this is just bad, plain bad.

why isn't megan fox in this one?  

wow, looks dumb! Megan Fox has the term 'actress' on her resume, though it may not mean much and is more than likely spelled wrong, it's there. The directors were obviously not interested in actors because from what I saw, it looked absolutely terrible. Movies that go right in line with this one:

Ninja Cheerleaders - http://www.imdb.com/title/tt0972857/
Zombie Strippers - http://www.imdb.com/title/tt0960890/
Amateur Porn Star Killer Series - http://www.imdb.com/title/tt0772152/

Just to name a few
