Solid old-school scifi. Predictable and twee but the dialogue is cracking. The 2D plot devices that populate the story (allegedly referred to as "characters"*) lack anything remotely resembling human but I guess that that could be the point. A solid train/bus/plane timekiller to leave behind in a hotel.
