The old 70s episodes are great!
Back in 2013 or 2014, Netflix had the first few decades of SNL available, so dad introduced me to the great stuff he used to watch when SNL was new. Yeah, it looks dated and cheap, but some of the writing is comedy gold. Plus it was fun seeing all the people who later became comedy legends in their early days on screen. I even got to learn about stuff like the Land Shark, Miss Emily Latella, the Lucy in the nuke factory, the Marine wedding, the Coneheads, and even Chevy Chase doing the fall. Wasn't always impressed by the music, but again, it was a different time.
So if anyone wants to see classic comedy stuff that launched many movies and decades-long jokes, I'd totally recommend the 1970s seasons.
