So, yeah Harmon stepped down for this season but will be the show runner again for both seasons 5 and 6. Looking back, I think I appreciate this season more with hindsight knowing Harmon will be back... but watching it week to week I think me and a lot of other folks were highly critical of this season because of that loss of creative direction, which has caused a lot of negative stigma around the season. I still think there's some characterization problems and tonal shifts this season that makes it less engaging than prior and future seasons, but I think as the season goes on it gets pretty great. So while it's probably mine and a lot of other people's least favorite season there's still a lot of fun to be had.
