The show started to somewhat heal after Season 7
The animation started to get more expressive
More good episodes and the good episodes having higher highs (Planet of the Jellyfish, Chum Fricassee, Ghoul Fools)
The episodes started to get experimental (Plankton's Good Eye, Face Freeze!, The Krabby Patty That Bikini Bottom)
