my reason is simple. I don't think there has been a good season since season 15. Season 21 has had a few good episodes but look at the bad ones. They are some of the worst ever. Season 13-15 was good IMO. So was 2-9 IMO. However with the quality of the last five seasons i assume this one will be none better. Besides look at some of the plots for this season. I think they sound bad.
