A journey into hell. This is absolutely one of the most macabre movies I have seen. It is very well crafted, but at times, tough on the senses. Pay particular attention to the two troglodyte females, their condition and apparent utility, to acquire a sense of the depravity associated with this culture, in which Kurt Russel and colleagues are trapped. The manner in which this movie is filmed, renders rich sepia indoor shades and detailed, almost pastel tone outdoor coloration. Visually, this is nicely executed. The characters and acting are more than adequate, with some slight, occasional over-acting from Richard Jenkins. Considerable thought and creativity are apparent in the visuals used to construct the horror, within which these characters are immersed.
