The story only works if Mari dies. It all becomes a Shakespearean tragedy where no one really escapes. Letting her live is a cop out and somehow seems to decrease the sense of the horrific crimes being committed.
I agree with OP that it only works if Mari dies. I don't know if horror movies are watered down but they're better viewing now days. The main problems with this movie is if you've seen the original because this as a remake doesn't follow the correct plot. And as you said Mari dying maters a lot to the degree to which the parents may be motivated. I think this one was far more realistic overall in every respect though.
Oh please. In the original movie this character dies but I'm so glad they didn't make a direct remake where you know every next step and turn. This remake is great and the story works very well
