Manatee

A truly fantastic film. The actors all seem to have learned their lines phonetically but compensate for it by making insane, wholly uncharismatic character choices throughout as they are torn apart by demons(?) in a nearly empty movie theater. Whether you're a person that likes a bursting pustule or someone that prefers a close up of teeth falling out, Demons has what you need. Trailer: I found it on Amazon (with the Shudder add-on) but I think it is also available on youtube.
