pretty much all season 8-9-10 are crappy except I do like Murder Smoke and Shadows (8:2) and Columbo Goes to College (10:1)

Totally disagree. "Columbo Likes the Nightlife" was a terrific final show and one of the best of the latter episodes. Good script, some solid detective work, a unique "gotcha" and a very solid cast. The common silliness that went on in the latter episodes (Columbo talking to plants, playing the tuba, etc.) was missing, which helped to keep this one focused on being good TV and resulted in a Columbo we rarely saw after 1978.
