No pun intended as always. This is quite the intriguing but also hard to watch stuff. Winning is everything - or as they also say: no one remembers who came in second (that is most definitely not a pun or innuendo - though sexuality does play a role here). It is about leading, it is about going under (there are so many things you can do - dad jokes or whatever you would call them - which in and of itself could be considered a pun).
The relationship between a swimmer and her coach is ... well always something that can make an interesting topic. Even more so, when it is as complicated as the one we get here. Then we have personal issues and rivalries and an up and cummer (is that a typo?). If you are not an athlete of any sorts you may not know what goes on behind the scenes - the power plays, the insane pressure ... and the own goals one has ... not always easy to achieve. As we know: there can only be one (or two if is a team sport - well that is how it usually works) ... again not an easy movie, with a lot of ups and downs (not just jumping wise) ... and a drama that has quite a few surprises for you too ...
