There are plenty of decent shows on network TV now I'm sure. The Goldbergs seems like a pretty decent show.
When I was a kid, I sat there and watched Alice because my parents did. That was a horrible frickin' show. Even 11 year old me thought it was stupid. But it was on the air for probably 7 years. You never see it in reurns either. Why? Because it sucked.
I tripped over "Alice" just recently while insomniac surfing on late-night TV.
You're right, it's completely unwatchable. The characters that I vaguely remembered as humorous? Yep, not funny. Vic Tayback did an ok job of playing himself, though.
"Three's Company" reruns are on fairly often. I surf through them; they're pretty much unwatchable as well.
