Great stuff. Python, Fawlty Towers, Blackadder, Mr. Bean, all really terrific.
Guilty pleasure: even the cheesy shit like Keeping Up Appearances and As Time Goes By.
More modern: British Office was good, and right now I'm loving That Mitchell and Web Look (Peep Show is a bit too crass for the wife).
"As Time Goes By" was hardly cheesy to me. It was one of the most charming series to air on Public Television. Judy Dench and Geoffrey Palmer had tremendous rapport as actors and Lionel's parents were a scream. Also enjoyed Mrs. Bale - one hell of a stand out performance.
Another favorite of mine was "Butterflies" about a woman who copes with her mundane life married to a dentist by flirting with a man she meets by chance on the street and then spends the rest of the time fantasizing about what could be with him.
Another one not mentioned was "The Good Neighbors" with Felicity Kendal and Richard Briers. I bought the whole collection. They play suburbanites who decide they want to live off the land and start a farm in the middle of the London suburb of Surbiton. Great stuff.
