A while ago, I realized that it's the Full House of adult sitcoms. There were other sitcoms that did what it did better, and were funnier, but you can watch it any time and you don't need to think too hard about it. It's like a Billboard pop hit or McDonald's. It just makes you feel good.
I give it a lot of props because of how iconic the characters are. The show has quotes for days and it was one of very few sitcoms that had story arcs and had the characters become different people as it went on. I actually believe that by the end of the show, the characters were all different people.
There's things I can't ignore that make it hard for me to put it up there with some all-time great sitcoms. If it wasn't for Living Single, the show wouldn't even exist. It took the same formula and was able to build an empire while some people know nothing about the show that came before it. I don't like how in the later seasons, the characters became a lot less likable and realistic. I don't like how sometimes, they would have these really stupid situations with no self-awareness of how stupid they were. And I don't like how much the Ross/Rachel shyt dominated the show. They should have put that to rest in season five and picked it back up in the last season if they really wanted to get them back together.
In terms of impact and influence, it's definitely a top five sitcom, but as far as quality goes, like I said before, it's more like Full House to me.
