I found this one fairly entertaining and Hanna Oldenburg (Emma) and Ralf Beck (Jim) were pretty effective in their roles. While this is a rape/revenge story that features two rapes, I wouldn't say the rapes were particularly gratuitous and they showed very little skin. LOL, me saying that any "rapes" were not gratuitous is a bit of a non sequitur, but as these things go in the cinema world, they really weren't.
The violent scenes were quite well done and special effects pretty decent for a low-budget film. I've certainly seen a lot worse and these were good enough to make their impact. I found the screenplay to be fairly original, with some good one-liners that are not usually found in movies of this type.
In the climactic scenes near the end I was impressed with the expressions that Emma emoted as she wreaked her revenge on Jim. She was simultaneously repulsed by the actions she was taking yet inspired to gather strength to do even more to him. Not quite Oscar-worthy, but that was a nice mix that seemed pretty realistic for someone who had never been so violent in her life...yet was absolutely driven by her hatred of the man who raped and tortured her.
It's pretty easy to toss off these types of movies as just another "seen one, seen 'em all" type of film. This one offered a little more realism that sometimes made you forget that this was a movie with a camera, director, lighting, sound equipment, etc. Surrounding the action. And I never overlook all that stuff, even when watching the most horrific slasher/horror type movies.
