Review of The Dive from Clausen's Pier

This movie was actually somewhat entertaining for the first hour and 10 minutes or so. But when she goes back home at the end, the movie goes completely off the rails. Carrie was already falling out of love with a guy she was engaged to who ends up becoming paralyzed due to poor decision making. Leaving him was a no-brainer. Because of the judgment of friends and the boyfriend's family, getting out of town and creating a new life was absolutely the right move for her. I get that her friend she left behind had problems, but we all have problems and I just don't see why Carrie had to stop everything in her life because her friend's mom went to rehab. Other than being moral support, what more could she have done? I really don't understand the motive to stay behind instead of embracing her new life, which seemed to have a bright future. Don't live in the past. Really disappointing ending.
