The Gist: When a struggling startup private dental practice needs money they subcontract to a night shift dentist who's a vampire with vampire clientel.
Clarification: The idea of a vampire dentist in a horror movie would make sense and be pretty decent if done right. I mean the guy could theoretically work nights and suck peoples blood without them knowing after he puts them to sleep, possible cause an outbreak of vampirism before moving to a different town and starting over. Do not look for that here as this is an absurdly cheep B-grade dark comedy that takes place in what seems to be an empty warehouse.
It's about as well written as your average elementary school writing assignment complete with bad fart and anatomy jokes (The two lead dentists names are "Moe Lars and Pierce Able"). The two struggling day shift dentists pretty much sexually harass every woman that comes to their office (in a G rated way) yet they still somehow have business. We won't even mention the running gag of the fact that delivery drivers always start off by saying that they couldn't find the place due to there being no sign yet the clients find it no problem.
Eventually the film then remembers that they think they need a storyline so after well over an hour of just people with different "comical" personality quirks coming into the dentist office and getting seen by dentists they decide to throw in a sort of love triangle between the vampire dentist, one of the daytime dentists (who switches to nights halfway through to help with the vampire clientele for some reason) and a blind woman. Again, elementary school writing assignment level so don't expect it to make sense or mean anything. In fact, since the movie HAS NO ENDING don't really take anything that happens in it seriously. This is literally an hour and a half of filler with no real purpose that just stops.
Female Vampire Factor: All the night clients are vampires but basically cartoony versions. Goth makeup, cheep fangs, black clothing and Dracula capes. All the female vamps (and pretty much everyone else in the film) are clients in the "waiting room" of the makeshift dentists office the film is located in.
