I remember TW3 very fondly, it was the last time Tom Lehrer was doing new stuff regularly and getting wide exposure.
I watch northern exposure reruns when I happen to run across them; they hold up well. I liked the show Thirty Something. I also have usually enjoyed Once and Again, which has just been cancelled in spite of critical acclaim for Sela Ward and the rest of the cast. Sela Ward also starred in Sisters, which I enjoyed, too, and which I was sorry to see come to an end. My husband and I used to watch it together once a week. Now I watch reruns of BBC's East Enders, which my husband calls my "open sewer program". I have a shameful weakness for these soapy family "dramas", which are actually a waste of time but I succumb to them anyway.
