A guy from a bleakly dysfunctional future casually robs and mutilates a peaceful past via his ability to manipulate time. Strange how we call it science fiction because time travel makes no sense. It's just magic brought up to date.
Well done if not hugely illuminating, but it highlights an interesting contrast between short and long films. Presumably the length of films has largely depended on the need for punters to feel they had their money's worth and making the effort to visit the cinema was worthwhile.
