Time Out says
While the childhood scenes are affecting, ‘The Kid’ loses its sense of direction when Lewis reaches adulthood. Like ‘Telstar’, this fails to dig deep into its protagonist’s emotions – in fact, it barely touches the surface, merely relating events in a plodding fashion. Friend is fine, but a prosthetically altered Natascha McElhone overplays it as Lewis’s monstrous mother – it would be comical, if the story wasn’t so depressing. Where’s a more convincing actress when you need one? In short, this is an inspiring story, but it’s badly told. Best read the book instead.
