I watched friends right from the begining back in the early 90's, and it was fantastic. Series 1 was outstanding, equal quality to that of Frasier. But as each seres came, it lost its charm. Each series got just as pathetic and insulting as the last. Its sad it went on this long, this dreadfully. All of its humour was drained come series 5.
But I have to say, I wouldnt not buy all 10 seasons. Theres a bond with friends, that very few TV shows can offer. I cried beyond belief when the series finale was broadcast, it was an end of an era. I may not have enjoyed the humour, but it turned into a soap for me, and I couldnt miss an episode. I had to catch up on all the stories.
