Query: Excellent Season

Finally season 9 has been released; my favourite season of Cheers. I especially enjoyed the introduction of John Hill, Sam's new nemesis. Furthermore the entire cast continue to play bigger roles, a trend which started in the 6th season. The Diane years were boring, as was Diane herself. For me the series begins with season 6, and season 9 is the series' height of creativity.
