For me it's Sunday TV that really sucks. Comes down to it, no night is exactly nirvana these days. Television might have sort of lived up to its potential many years ago, but it doesn't even come close now.
I rather like that there isn't much recording on Saturdays so I have some time to catch up a bit on the stuff that's recorded all week, before the Sunday rush hits. I always have quite a bit on Sundays.
Funny how we all have such wildly different taste. I had way too many options last night. As mentioned Dateline, 48 Hours, two Colombos, my PBS had Endeavour, Mannix, Combat, The King's Face (Korean Soap Opera). To me, weekends can be the best.
