The movie isn't flawless. The jarring opening deflates into turgid exposition, the romantic subplot requires a hefty bit of spousal cluelessness, and the disorienting action sequences rely too heavily on quick cuts. But it still hangs together, a better Hills Have Eyes. (Though, in this one, the eyes are vestigial. You'll see.)
Sample dissent, via RottenTomatoes, comes from Claudia Puig of USA Today.
When it comes to female bonding and physical exertion, one wonders, why couldn't the group have just passed on spelunking and spent the weekend attending yoga classes at a spa?Thank you, Claudia, for reminding us that women are just walking stereotypes.
