Well, the short version is the vampiric version of Romero's "Night of the Living Dead". The spreading infection. The group of dysfunctional family members. The house under siege (granted from within instead of from without). Add a solid dollop of Edward Albee's "American Dream" crossed with Lynch's "Eraserhead" and you MIGHT get the idea. It is gorilla film-making. Have no doubt about that. Overall, I still can't decide if I liked it or not. There is no adherence to mythology (in any universe I've seen vampire films from) so you kind of have to suspend disbelief over a deep pit of boiling lye. But, if you can, you might find it interesting. And, even if you can't, it has a certain "Train Wreck" like charm.
