Although The Simpsons season 36, episode 7 brought back a villain from a standout season 35 episode, it is not a supporting character that viewers are likely to expect. The Simpsons season 37s renewal has not yet been announced, but things look good for the shows future. From Vulture to YouTube, critics across the Internet have started to argue that the long-running series has been in something of a creative renaissance since season 33. Seasons 34 and 35 enjoyed substantially better reviews and fan reception than seasons 30-33, which were largely derided as the shows new nadir online.
