The Pied Bagpiper

The first few season, sans a few 'questionable' morals, are a considerable showcase of entertainment value, intrigue, themes, storytelling and character work. After the conclusion of season 4, however, the writing quality drops, vast potential is wasted, most of the characters lose their compelling characteristics and the morals veer even more into outright toxic lessons. The finale is the worst of it all, with the subsequent movie offering nothing new.
