I thought Seinfeld was well written but terribly irritating. I saw a lot of them back in the day but never with much enjoyment. Friends was abominable - a celebration of empty blandness. To be honest I've never understood the enthusiasm for sitcoms. Saw quite a few Big Bang eps they were intermittently funny but not something I would ever seek out to watch. I think I prefer British humour - Black Books and Blackadder were amusing although I wouldn't call myself a fan. If I want a laugh I generally watch bombastic commercial news broadcasts.
