Just stopping in to say that I’ll be mostly avoiding this thread as I don’t see any way to read this discussion without shows I’ve been planning to see getting very spoiled.

That being said, while I’m here; I’ll bite.
Everybody Loves Raymond had a perfect ending if you ask me.
The Office fell apart. ‘Nuff said. James Spader contributed to one of the funniest episodes of the series though, but other than that, the last season or however long it went without Michael Scott was not worth it.
Seinfeld I was good with. They really couldn’t have done much to end that show on a serious note. The show never took itself seriously and suddenly people wanted a real ending. The ending was dumb, but it was perfect for the show.
