This film is as masterfully executed as Wong Kar-wai's "In the Mood for Love", but it examines love through a much harsher lens and with unforgiving proximity. Wong's unparalleled attention to detail makes this film feel true to life, even if some scenes are difficult to watch. The symbolism of the tango shows that Wong has his finger right on the pulse of this relationship, which is characterized by kinetic energy and antagonism. This film is visually striking, and deeply moving.
