I saw these on Facebook...
LOST. Stargate SG-1. Battlestar Galactica. The Mandalorian. Deep Space 9. Babylon 5. Stargate Atlantis. Stargate Universe. Buffy the Vampire Slayer. M*A*S*H. Dark Matter. All 2 to 3 times. These are all great shows. LOST is in a league by itself. Battlestar Galactica and The Mandalorian are close.
Deep Space Nine has the best set of characters of any Star Trek show. Stargate SG-1 starts out a little rough but mostly gets better with every new season. The last two seasons are just amazing. Buffy starting around season 4 had one special episode every season that is experimental but also puts your jaw on the floor. Buffy takes midway into season 2 to get really good. Season 1 looks low-budget, and one only needs to watch the beginning, the middle, and the end. Babylon 5 had some amazing story arcs.
