Season 17 continues Al Jean's zombie Simpsons run, now in its 5th season. As you may note, this is the first season which contains absolutely zero episodes scored 8 or above - every other season had at least two such episodes, even Season 1. Still, this season scores higher than Season 16 as Season 16 contained several very poor episodes, while Season 17 contained just a couple. Despite not having a really good episode, that comparative lack of bad quality was enough to keep Season 17 from being as bad as Season 16.
...you can tell how low things have gotten when a season's only saving grace is that it wasn't as bad as the previous season, and only as a whole.
Season 17 Overall Score: 6.63
