The plot never thickens, but, it interchanges genres...

I was excited with this movie's ability to confuse me. At times I forgot I was dead in the middle of suspense and horror, as the daughter reveals that she's pregnant, the mother reveals that the son's father is Allen Rigman, and as the father's affair with Sally Schmidt is abruptly insinuated then introduced, I absolutely flat-lined amidst being astonished.
