The Leftovers. Really great premise, the acting and writing is fantastic, etc, only 3 seasons so I didn’t have time to get burned out. Watched it a year or so back and I’m already thinking it’s time to rewatch
Edit, gotta mention Get Smart. My parents showed it to me when I was young and it has really shaped my sense of humor in a lot of ways. Very wholesome (although some episodes are very much a product of their time).
