It is quite simple. Friends is a comedy of very basic humour aimed at teenagers and young adults, with unsophisticated sense of humour.It is also painfully obvious that towards the end, they were desperately trying to make it last 10 seasons, most likely so they could say they beat Seinfeld's 9 season run. The trouble with this is, Seinfeld had 9 amazing seasons with great writing, Friends had (and I'm being very generous here) at most 5 or 6 OK seasons and then 4 abysmal seasons.It became a soap opera with recycled humour and recycled character traits that weren't that good so start with, then got worse at the 100th time you saw them. I find it so hard to understand why people rate this so highly. It is truly awful.
