Park Seo Joon is known for his ability to swing from dramatic actor to completely silly faced comedian, while still staying fascinating to watch no matter what he is doing. This movie follows the progress from sarcastic, agressive coach to caring and leading coach therefore the movie seems to be in two parts. Also every Korean movie will show you the back stories for its characters. Nothing is ever linear and it might take some getting used to for new watchers. I giggled and smiled the whole way through. A completely enjoyable movie.
