RE: Send Help - Did the movie have a fair finale?

It's true that some movie or TV series endings leave a strange aftertaste, but occasionally we see an ending that fits perfectly and makes a lot of sense within the established plot.

Here, the protagonist is someone who already has certain imbalances and problems, but the people around her seem to enjoy humiliating her. That's usually a bad idea; it's like if you beat a dog until it's fed up and the dog bites you, then you complain that the dog bit you... without acknowledging that you yourself were the direct cause of being bitten.

I've seen records of cases like this, and I see it in the news too: a person who crosses the line they could bear and commits a homicidal act. I can't justify the crimes committed in these circumstances, but I must admit that I can understand how they were triggered. I even wonder if I wouldn't have snapped if I were constantly humiliated like the people who suffered the abuses documented in criminal records.
