I think I started it because I wanted something mindless and non addicting to watch now that school has started. But, because the episodes are only 22 minutes, it was quite easy to gobble up many episodes an evening.
At first I was incredibly put off by the laugh track, which seemed so jarring and disruptive. I eventually got used to it. So much so that by the end I really didn't notice it at all. I also remember that I used to find Kelsey Grammer's overacting in this show to be insufferable, but not only did I get used to it now, I began to see how it was effective.
I really like Frasier. I love how it mixes a bit of wry, verbal humor with very traditional broad physical humor, and classic wacky plot structures. Niles and Frasier are great together. I was shocked to learn that they added Niles' character at the last minute, that he wasn't part of the original concept. I cannot see the show working without him. The PAIR of comically ostentatious snobs is somehow hilarious. And their similarities serve to enhance their individual characters by bringing their differences into focus.
There is also something sweet and endearing about the family dynamic -- The grouchy father and the two competitive grown boys. The other characters are good, and most of the episodes are pretty tight with many, many funny moments. The last three seasons are not as good, as Niles and Daphne get together, and some of the storylines wrap up. Oh well, it happens to the best of them.
