Hmm not me in every case I have to say, maybe I'm not Mr Average which I can readily agree may be true, ahem. But there are many well crafted sitcoms I love to watch that aren't wildly entertaining, but I just love the quality of writing and/or acting or sometimes just the sit or setting.
To The Manor Born which I'm enjoying on reruns now is good quality dullness in relative sitcom terms. Hesitate to say even the highly regarded WHTTLL is not the most overtly funny of sitcoms if you analyse it in terms of lols but only a complete noodle nut would deny it's a classic. I think there are many more true sitcom fans who appreciate a well made one of any hue than a bunch critics and journos alone. RIP George Cole btw.
