Unholy Cow!
Was not expecting this from Kevin Smith (Clerks / Mallrats / Dogma etc.), as this doesn't look or feel like one of his movies... In fact, it doesn't even look or feel like the DVD cover / poster art would lead you to believe this movie was going to be...
...Because going by that, you may be expecting a Robert Rodriguez / Tarantino-ish type of hillbilly / horror chop up festival of the gross out kind of affair.
(Funny, I watched Tucker And Dale the other day, bought among the same batch of DVDs, so was expecting something a little more along those lines)
No, this is a more slow burn, unsettling, even serious (in premise) affair regarding a very Waco incident reminiscent movie, with a disturbingly believable religious sect entrapping a trio of horny teenagers who have one trekking on a promise of sex, causing the ATF (think I got that right?), led by John Goodman's agent to lay siege to their estate.
The brilliance of the story is that there are no clear heroes in relation to "the villain", as the government orgs are ever more dubious as it goes.
Michael Parks, as the cult's leader and religious head, absolutely steals the show as the quietly maniacal, manipulative, and superficially affable and charismatic top nut job, and this whole movie hangs on this faultless and stunning performance.
Put the idea of "Kevin Smith movie" out of your head, as well as the notions and impressions that the cover / DVD art may give you, and you will see a very subtly brilliant movie when you watch it.
