If you loved Thor: Ragnarok, delve into director Taika Waititi's back catalogue with this brilliantly funny and heartwarming film, which he wrote and directed. It tells the tale of a juvenile delinquent desperate to get child services off his back and the grumpy old man who ends up his guardian. For reasons best left to the film to explain, they end up on the run in the New Zealand bush, and much hilarity ensues.
