"Duncan" (Liam James) is a typical fourteen year old boy. He keeps himself to himself, and isn't greatly looking forward to his family holiday with mother and her boyfriend and his older teenage daughter. Determined to get away from this domestic bliss, he heads to the "Wizz" water park where he strikes up a friendship with one of the animal keepers "Owen" (Sam Rockwell). The latter sees something, perhaps of himself, in this younger lad and allows him to help him. As the summer progresses, both help the other to find an inner strength to deal with their demons - and, gradually, a newly empowered "Duncan" emerges ready to assert himself a little more. Whilst this isn't a great film, there is something about James's strong and personable performance that merits watching. His teenage angst is cleverly, subtly even, presented to us and his relationship with Rockwell, not an obvious friend for the boy, evolves by degree - and not always positively, either. There is way too much dialogue, and I found the family sub-plot with his over-bearing step-father "Trent" (Steve Carrell) and his really irritating daughter "Steph" (Zoe Levin) whom would cheerfully have left in the shark pen, got in the way of the intensity of this otherwise quite engaging exercise in bonding and maturing confidence. Worth a watch.
