The last show, “Columbo Likes the Night Life” is a strong finale to a long, entertaining career going back to the early 1970s (when I was finishing university). He retired at the top of his game (a year after I retired from teaching).
It is dazzling image-wise and sound-wise, and features several rave club scenes, strong male and female villains, the usual Columbo trademark humor, a funny interview with a hotel maid about a toilet, a Mafia henchman, an accidental death, a nasty murder, koi fish, and a high-tech resolution. Well-directed and acted. A good script and atmosphere. Not to be missed.
(Falk, incidentally, lived 8 more years after the series.)
