Black Rock, after just around twenty minutes or so, begins dragging, and that doesn't really bode well. The story's fine, and the characters feel real, but when everything's said and done, this movie is a bit below average. Might be worth one viewing, but probably no more than that.
What feelings did Black Rock elicit in you?
