'Girls on the Road' is another one of those underrated but perfect Grindhouse movies. It intelligently uses cinematic techniques to create comedy not just through performance, but through editing, directing, cinematography, sound... The performances are also surprisingly very strong for a Grindhouse film, something that makes the film that much more enjoyable.
I highly recommend this film to anyone who just enjoys having a nice laugh at horror/comedies. You will not be disappointed!
