Pointless and cowardly

In the original piece, the woman decides against acting against her rapists and lapses into religious lunacy and self-flaggelation.

That is stupid, but at least it's an explanation.

The writer of this remake evidently feels shy about the out-dated religious aspects, so simply left those out, only to replace them with... nothing. A blank space.

Although it becomes clear towards the end, when we see Paulina's "martyr's walk", that the explanation is basically the same.

The only thing that never becomes clear is what the point of this movie is.
If there is a message, then it's a terrible one. If there is no message, then it's the most boring piece of exploitation I've ever watched.
