Unlike lesser directors who would have tried explaining the workings of Da Fu's mind to their audiences, writer/director Xue Xiaolu instead wisely uses his affinity for the world underwater- swimming with the turtles and dolphins- as a motif of his state of mind, different and yet beautiful in its own way. These scenes of Da Fu's graceful diving in the aquarium, where both he and Wang works, are captured in a ravishingly lush blue palette by Christopher Doyle's cinematography, set evocatively against Joe Hisaishi's score and Yee Chung Man's production design.
Perhaps the only missed opportunity here is Xue's subplot involving Kwai Lun-Mei's circus clown turned friend to Da Fu. Not enough time is spent delineating the friendship that develops between the two and the result lacks credibility, especially since Kwai's character seems too ready to accept Da Fu's quirks and idiosyncrasies. Nevertheless, the film's focus is really on the father-son duo of Wang and Da Fu- and in this regard, succeeds tremendously thanks in no small part to Jet Li and Zhang Wen's sublime yet powerfully convincing performances.
Yes, you should know that even without his fists or kicks, Jet Li still proves to be a magnetic actor with his unassuming portrayal of an ordinary man looking out for his son while looking death in the eye. But really, this film is more important and more significant than just being Jet Li's first non-action role- it is an extremely moving story of a father's tireless love for his son, no matter the odds, no matter the challenge. Especially to the parents of children with special needs who have given themselves continuously to the care of their kids, this is a tribute to the depth of your love, the depth of your heart.
