The REAL reason the show went downhill in the last few seasons.
.
People on this board keep wanting to blame the writers, but that's not the reason the show went into a decline.
Here's the real reason:
When Debra Messing got noticeably pregnant (season 6), she couldn't work the long rehearsals, so James Burrows cut down on rehearsal time for the entire cast. A very large percent of the former very extensive and rigorous rehearsal time simply got removed.
The thing about comedy -- especially comedy at this level of quality -- is that it needs extensive rehearsal, and under someone as rigorous and as perfectionistic as Burrows.
So the quality of the shows immediately started to decline, due to lack of rigor and lack of rehearsals.
(That's also when they started loading up on guest stars, to replace Messing in her absence.)
Unfortunately, even when Debra Messing returned to the show after her maternity leave and so forth, the show kept that short and lax rehearsal schedule because the entire cast had gotten used to it and gotten lazy.
So standards went out the window, and the show never recovered the level of excellence it had prior to Messing's pregnancy. Sad but true.
I kind of blame Burrows for this. He could have kept up the standards and the rigorous rehearsal schedule if he had wanted to -- but he didn't. I guess he got lazy too.
To me the last watchable season is S6. The seasons after that are just boring, or cringe-worthy, or both.
