Kid Coulter in my opinion was a good romp, serious enough to be a good adventure, funny enough to lighten the mood. The kid was a nerd uncomfortable in the outdoors, more into computers and chess. When confronted with a chance to try something new, a physical challenge, he backs down, having no confidence in himself.
He had to get comfortable pretty quickly, and learn to be self sufficient. the viewer is treated to a light hearted survival story, with elements of danger and fun. Not for the seriously literal minded viewer. Viewers willing to suspend disbelief and let the film be what it is will enjoy it. It is a family film after all, meant to appeal mainly to the younger audience or at least the young at heart.
