I never really cared much for David Jason as a comedian as he was mostly in series that went for cheap laughs and fairly one-dimensional acting. So I was really very pleasantly surprised at how great he is as Jack Frost. Frost is an interesting round character but does not dominate the film completely with his personal quirks. I particularly like the subtle built up of erotic tension between him and a visiting police woman. The story is very good, nothing is what it seems and you can't help being surprised at all the twists and turns. At the end there are a hell of a lot of coincidences but at the end of the day the solution is acceptable. For a TV show it's also quite well directed in terms of nice visual ideas.
