That 70’s Show is a cult classic TV show and a hit on Fox but the decade later try-to-hard show That 80’s Show? Too much. Cancelled after one season the show was really it’s own #TBT (before that was even a thing). That 80’s Show even starred Chyler Leigh (Supergirl), Glenn Howerton (It’s Always Sunny In Philadelphia), and Brittany Daniel (Sweet Valley High) in 2002.
