Usually when a show declines in quality, it stays that quality until it ends. But there are exceptions where a show can bounce back and be as good as it once was. What are some cartoons that you feel, were revived from Seasonal Rot (http://tvtropes.org/pmwiki/pmwiki.php/SeasonalRot/WesternAnimation)?

I will say that Season 19 of South Park was an improvement after numerous "meh" seasons before it.

But it's too early to tell if it was just an anomaly or truly a revival from "Seasonal Rot."
