How bad is it? It's dull.
Should you see it? No.
I like gay vampire porn as much as the next guy (well, probably more, unless the next guy has seen some), but this fails badly. It's about monks who spend most of their time having sex with each other and whipping each other - the two are not exclusive - and then there's a vampire thread to the story that could be removed with virtually no change to the plot. It's slow. It's pointless. Some of the camera work is okay, some looks like a student trying to be arty. The acting is underwhelming. The dialogue has some amusing clinkers, but not enough to merit watching this.
