This is a hard one to define. On one hand it is relentlessly and unnecessarily brutal. The rape and violence is graphic, disturbing and drawn out. And by drawn out I mean it lasts for half an hour.
But on the other hand it is never trivialized. Jennifer is traumatized and given sympathy from the film. Not once does the film suggest that what happened was okay, and perhaps it needs to be so repugnant in order to show the true horror of it all.
I can't really figure out where this film falls. It's certainly not a light watch.
