I think that shows like Friends, and another show I love HIMYM, focus on a very specific time of life, and that's what makes them so enjoyable and relatable. There is a beautiful time of life (fortunately, that I'm in right now) where you can hang out with your friends a lot and do a lot of things together, you can be free and spontaneous and have a lot of fun. And like in the shows, this bridges into marriage and even the early stages of parenting. But naturally, it's a finite period of time. And it gets replaced when people move out to the suburbs to raise their kids, or move to different cities to work, or start working longer hours at managerial positions, or have multiple kids, etc. And that's not a less beautiful stage of life, I hope, but it's different. It's less conducive to the TV sitcom mode of presentation. I think the ending of Friends was lovely, I don't think ending differently at another point would have helped it.
