Black Rock is a wilderness survival horror. One is immediately reminded of body of films that began with Deliverance (1972) and in particular something like the British Wilderness (2006), which had a similar plot about a group of troubled teens abandoned on an island and being hunted by a psychopathic ex-soldier. Black Rock could perhaps be considered Wilderness with a Chick Flick spin where the targeted teens are replaced by a group of women friends.
I was reasonably impressed with Black Rock as it started in. The tall angular Katie Aselton is a new actress to me and gives herself the lead part at which she holds up fairly well. I had failed to be impressed with Kate Bosworth in anything I had seen her in before where she just seemed another blandly anonymous blonde of no particular distinction, while Lake Bell had only seemed to be cast in the type of bubblehead parts that usually get given to Cameron Diaz. Katie Aseltons strength as a director is in being able to give either actress a part that allows them to step out of prior typecasting. There is the sense that Bosworth and Bell have relished the chance to shuck the glamour and makeup and simply improvise playing ordinary women. The trio of them play off each other well, creating a strong interaction and roundedness to the girls and their friendship. I was quietly surprised about what either actress manages to find during these early scenes.
I was still liking Black Rock about the time that it introduced its antagonists. Mark Duplasss script touches on the great American psychic divide caused by the Iraq War one is reminded of the late 1970s/early 1980s and films like Taxi Driver (1976), The Deer Hunter (1978), First Blood (1982), Combat Shock (1986) and Full Metal Jacket (1987) where those who came back from the Vietnam War were seen as disturbed and mentally fractured by what had happened. Duplass keeps what happened in the field vague beyond the suggestion of atrocities caused by the three soldiers. The three soldiers are passably well crafted, with Jay Paulson standing out once he gets to go off the rails. This largely serves to get Black Rock where it wants to go, which is to become a Deliverance/Wilderness spread across the sexes.
Alas, by the time it gets to this point, Black Rock becomes a big letdown. Katie Aselton gives us various scenes with the three women on the run and being hunted. Alas, you get the feeling that she has never watched many of the other films in this particular genre niche. Either that or she conceived Black Rock solely through a Chick Flick niche unaware that it would play out to a horror crowd as well. This is a type of genre where you expect the game of survival to be pushed for an intensity or else drawn out to a level of unbearable brutality. The disappointment is that Katie Aselton seems disinterested in pushing the survival scenes for much at all. The film feels like it is only getting started before she abruptly winds it up. You come to the end thinking Is that all? What a waste of potential.
