"Frasier" is probably one of the most intelligent and well-written sit-coms ever produced in this country. To find a series as well done, you would usually have to look to the Britcoms for stuff like "Fawlty Towers" or "Father Ted".
Boy, I couldn't agree with you more, and how refreshing it is to hear someone else who thinks that. Thought I was a "lone voice crying in the wilderness". Haven't seen "Father Ted", but really enjoy most of "Fawlty Towers".
True, it was a very funny and entertaining series. Unfortunately, "Frasier" did get tired towards the end of its run. TV shows probably weren't meant to go on that long. Keeping it going too long meant too many attempts at bedroom farce and too many "What stupid thing will Frasier do this week" shows. But Kelsey Grammar was talented enough to make even a lot of the more stale plots work.
