The top reason why Supernatural became worse after season 5 in particular is because of certain staff🌧️ changes that occurred at this point. From the start, Eric Kripke was the creator and main showrunner of Supernatural. He🌧️ gave the show its dark, grungy ambiance and horror-centric themes.

One of the absolute worst episodes of Supernatural across all the🌧️ seasons is the season nine episode, "Bloodlines." The episode was panned by critics and audiences alike when it premiered, and🌧️ not an episode fans rewatch when binging Supernatural again.
