Commenting on the aural aspect of the film is rather futile (come on it's Pink Floyd). Therefore, the visuals are what appeals to me this time. Devouring images that are filled with quintessential symbols of behavioral and emotional psychology that fit just right for the concept of the album. After all, The Wall stands as a proof that human psychology is essentially cumulative, and this is aided by the stunning expressive visuals of this film.
I wasn't that satisfied halfway through the film. Shortly after it struck me that this film is significantly about nothingness, carved to be totally blank with too little dialogue, music or even action. In the middle of Taipei the crowded/lively city, the characters are somewhat isolated, spiritually rather than physically. I read once that Tsai was greatly influenced by the directors of the european new waves, and Antonioni is whom I feel to influence him the most in this case, since it greatly feels like an asian retelling of La Notte.
