Directed by Herman Yau, best known for his CATIII work - this is quite the departure. It's a simple & sweet tale of two young lovers (Cecilia Cheung & Nic Tse) who lose their memories in an accident, and are exploited by their selfish councillor mother and a triad don respectively. Master Q and Potato, feeling responsible for their accident, look out for their best interests.
I'm sure most people know that Master Q & Mr Potato are HK's first fully CG characters, and they're pretty well done from a technical standpoint. Not brilliantly integrated with the real world at all times, but animated with character. In fact, they blend better with the real world than the real actors do with them. With the exception of Nic & especially Cecilia, the other actors in the movie obviously have real trouble acting into 'empty space', and tend to resort to overacting to compensate. Perhaps this was deliberate, but the overall feel of the movie ends up like a Children's BBC production. That's not to say that it isn't enjoyable, and raised smiles throughout, but it never reached a laugh. Worth seeing, but not rushing out for. Rent or borrow :)
