I dont believe it. There is no way it ever getting good again.

While certainly not as good as the first 9 seasons (and the show will never be that good again) the quality is definitely the best it's been in the HD era and has episodes of similar quality to seasons 11-16. 

Even throughout the bad seasons there are gems here and there, what's changed is that the consistency has improved so rather than 1 or 2 decent episodes a season the entire season is good enough with a few stand out episodes.
