Edward Yang protégé Chen Yi-wen makes a super-confident directorial debut with this snappy exercise in overlapping narrative. Four chronologically shuffled chapters introduce us to the main players: a film producer who is having an affair with the studio boss and an aspiring director; a thoughtful gangster (the dullest strand); and two kids, Kai and Jiajia, whose ill-advised car jacking prank collides social barriers. It's funny, clever stuff, but never excessively or incestuously cinephilic - the youngsters' ambiguous unconsummated relationship gives the film its heart.
