This was just bad
After the first two installments this went downhill real fast. The main character became extremely annoying to the point where I almost came to the point where I started rooting against her. She was very weak. If it weren't for the other characters she would never have survived. She repeatedly had emotional breakdowns.
But the ending was just terrible. It would appear that either the author or the screenwriter didn't know how to end it. It was predictable and looks as if it was finished in a hurry. I kept waiting for it to end but it seemed to continue on forever. What a waste of 2 hours.
