I love 90's trash
Other feel goods:
Seinfeld
The Simpsons
I can watch those any time any day, the jokes never get old and they aged wonderfully.
I've always found Everyone Loves Raymond and Home Improvement to be really comforting as well. There's just something about Tim Allen and Ray Romano that makes me feel right at home in those middle class suburbia sets and settings.
honorable mentions because I can never just pick two (or 5 haha):
fraiser
curb your enthusiasm
the sopranos
breaking bad (kind of a weird choice but I've watched BB like 7 times all the way through and I never get bored lol)
