So a few years back I wanted to watch Frasier because I had never seen it before, and got about a season in before I realized I didn't understand all the backstory references I was missing from Cheers. I went on a massive binge and watched all of Cheers, and man was I pleasantly surprised at how amazing it was. You can see the inspiration for so many shows just based on random episodes of the series. I will also say that some of it has aged horribly, especially the way Ted Danson treats women. Not just sexually, but he's a physically abuse person and there's like laugh tracks and s*** behind it. Not very cool tbh
I will say that the writing does have its down seasons, especially when Shelly Long leaves the show. I'd say that's a spoiler but come on the show's been over for 30 years.
