That's about it. The race scenes were shot pretty decently. They grip the viewers at the edge of their seat. The songs by Jay Chow are pretty good. The movie is funny. It was set and filmed in Japan, yet all the dialogue were in Cantonese. What else is there to say?
Jay Chow was pretty good for his first starring role. He gave a believable performance. Anthony Wong is his same reliable self and Chapman To again provides comic relieve (seems like he is typecast now).
The movie did not follow its inspiration, the manga. Even though Jay Chow's character is low-key and mild-mannered already, in the manga the character is even more mild-mannered and even less intense. In the manga, the dad seemed to be more responsible and nicer. That does not matter though, because the races are entertaining enough. That is one of two reason why people pack the theaters to see it. The other reason? Jay Chow. Do not underestimate his draw power. This guy is an idol in Asia. Whatever he do is gold.
This film is made for entertainment purposes. No depth. No plot. Just watch it and have a good time.
7/10, because it is entertaining. Take that out, a 4.
