Am I the only one that thought the coach hugging her and kissing her forehead at the very end was super-f*cking creepy? He's an authority figure and she's a high school girl. If she was my daughter I would throttle any middle-age man showing her that kind of physical affection. I thought coaches were fired for getting that close to young female athletes.
you also have to remember if it wasnt for his willingness to train her she wouldnt be where she is today. especially with her condition, you can somewhat understand that through all the trials and hardships there would be a father-figure like bond between them.
