The two "bad guys" were basically Leatherface from TNG split out into two individual characters and without the chainsaw or skin wearing fixation.
The movie didn't constantly show them constantly getting beat, that's the difference. It was implied from the bruises and the doll collection, also how she was made to sit like a doll.
That's why it's not torture porn - it wasn't graphic like that. The most graphic part for me were the 2 cops who pulled over to rescue the girls out in the field.
Now that I think about it -- this movie was more like Texas Chainsaw Massacre strictly from a point of view from the victims, with a psychological spin
That's why you didn't like it
You might have a point...:yupyup:
