Extremely unsettling, which, as an adult, is precisely what I crave in a horror film. Some have said this movie is slow, but that's how family breakdowns occur tiny fracture by tiny fracture, until a major bone goes compound. This is a movie I've seen twice already, and will watch again, because there are things you will miss and catch upon repeated viewings. I won't give the ending away, but it's well worth the price of your waiting. I easily give this five stars. A true horror classic.
