The most boring and senseless cliché of cinema - the car chase - is here given a truly surprising, clever and entertaining twist (no, I will not spoil its nature here). The movie is worth seeing for this sequence (the best in the movie) alone.
It's also interesting, and somewhat chastening, to compare this sequel with the original movie to see how far towards political correctness the Dirty Harry character has moved. While in the original, Harry is presented (at least initially) as an intolerant racist, here it is the Lieutenant that is presented as racist, seeing Harry's partner condescendingly only as a "token ethnic" whose pairing with high-profile Inspector Callahan will be good for the police department's public relations image; Harry relates to the Chinese officer in question as "Al", an equal, from the start, and mocks the Lieutenant's attitude.
