To me the relationship between Stamets and Culber felt like the single island of humanity and goodness in the four seasons I almost got through. And then they fridged Culber, only to then bring him back with mushroom trauma. Not really the woke thing to do. Adira and Gray just seemed kinda pointless from what I remember, despite the somewhat interesting backstory.

What I found forced and entirely unnecessary was Lt. Connolly in the first episode of the second season.
