I found this movie to be very good .
It is a horror/comedy movie with the Foo-Fighters with a metal overtone throughout the film.
There are cameo appearances by Jeff Garlin , Lionel Richie and Kerry King of SLAYER !!!!!!!!!!
I would give this movie a rating of 88 on a 0 to 100 grade scale , very entertaining .
Dave Grohl really is outstanding in this movie !
