If you're thinking of young ladies taking their clothes off, then you're for a rude awakening because these ladies are baring fangs, sure, but they do it for the comedy... and not so much nudity is to be found in this case.
But that shouldn't stop you from giving this movie a chance, because it acts pretty much like the Simon Pegg/Nick Frost duo of Shaun of the Dead, following two guys who decide to go hiking in the more lost parts of their country. There, they learn of an ancient curse that turns women who reach 18 into lesbian vampires... and guess what? Some of them happen to be around :)
As far as movies go, this one is pretty decent: it doesn't take itself seriously, it has a nice sense of visual, the ladies are... well... they are awesomely pretty, and once they turn into vampires, they act quite sexy (think Sigourney Weaver in Ghostbusters, showing a bit more skin) and get chopped a few minutes later... the actors do get the job done of making us laugh and give believable performances to their two-dimensional characters (although they do it with style).
Special features are not that long, but since you can't find them on many pages, here's a complete list:
Audio commentary from the director, the Fletch Meister, Crying Blood music video, Making of, webisodes and theatrical trailers. In total, without the commentary, you're off for 45 minutes of features, which is a nice thought to actually have included some.
If you're in a specially kinky mood, or if you're around Halloween, this title should get you plenty of laughs and skin, without showing too much.
