Nothing good in particular about it
I think this film is overrated. Jay Chou trying to be cool throughout, could have shown a little more emotions rather than be like a walking robot, if that's what he thinks is cool. The racing scenes did not provide much adrenalin rush either. Besides it was really silly and childish when Jay Chou and Itsuki fight. Even the fight scene looks just like kids fighting, while they were in fact mature grown-ups.
Overall, it was a mismatch of roles, casts and storyline.
