Yeah, it's all pretty bizarre, strange, and very unsettling. I won't say I liked this film, because I'm not sure if I did or not, it's that creepy. I found the scenes where the father was being abusive to the women, and he abuses all of them in on way or another, to be very hard to watch and sickening.
I'm sure this film is symbolic on some levels because what it comes down to is the film is about control and the lengths some will go to keep it. So, draw your own conclusions after you see it, and I do recommend you see it because it's so fucking odd.
*****UPDATE*****If you've never been to the south and you insist on making derogatory comments about it by claiming the this film sounds like something your stereotype loving ass might find in the deep south, then please by all means kiss my ass. Your 'joke' isn't funny and it shows you to be a clueless idiot. Seriously, go fuck yourself if you think the south is the way it is portrayed in the corporate media.
