The Mermaid (the Chinese movie that came out this year)
It's decent. The plot is completely predictable (seriously, just start guessing, you'll probably get at least 80% right), but there are plenty of laughs. If you enjoyed Stephen Chow's recent writing and directorial offerings, like Journey to the West, Kung Fu Hustle, and Shaolin Soccer, then you'll probably enjoy this one. Though like Journey to the West, the humor is noticeably darker than his earlier works. For example, there's a scene where an octopus mer-man's tentacles are grilled, chopped, ground into mince, and eaten, all while still attached to his body, and all while he's standing there trying to look composed. The whole scene is played for laughs. It's like, you'll laugh at the funny scenes, and then after the movie is over you'll think back upon what you just laughed at and feel rather bad about yourself. Still though, it's a rather likeable film. Perhaps not quite as good as Journey to the West, but it's still worth a watch if you're a Stephen Chow fan.
Also the female lead is really hot and I hope to see more of her.
