Demons

Director: Lamberto Bava

IMDB: http://www.imdb.com/title/tt0089013

Review: Meanders a little but delivers enough strong tone and schlocky fun that it remains enjoyable.

Watch it if: You're ok with a lot of over the top gore.

And if you liked: The Neon Demon, Berberian Sound Studio, The Evil Dead, Return of the Living Dead
