I don't understand the high ratings. It's TRYING to be bad, and somehow even fails at that. There's nothing smart, funny, or interesting about this. It's got Adam Sandler-level writing and Steve Carr-level direction. The story is just disjointed but not in a "weird and fun" way, just in a "so...how do we write ourselves out of this corner and into the next?," kind of way. Save your time, go watch some real schlock and have some fun elsewhere if that's what you're looking for, or go watch some Blood+ or even effin' Underworld if you just want some fun vampire action with an actual story and interesting characters. This is gonna offer you none of that. I think most people who are rating this highly are doing it based off of recommendations or having had fun with their friends while this was on in the background, 'cuz there's no way this is worth a watch otherwise -- and even then, there's tens of dozens of movies and shows that could fill that purpose WAY better than this.
It's just...not fun, not interesting, not smart, not engaging, not stylish, not raw...it's practically nothing lol.
