I finished watching Transparent Season 4 and I haven't really come to a full conclusion yet about what I thought.
I do feel like it was the weakest of all the seasons. The episodes were shorter and the pacing a bit too fast. Also, unlike it's previous seasons, it came across as a bit heavy-handed with its politics, which is not something I like seeing in stories, since it takes away from the narrative itself, and the characters. It's like how I felt about Orange is the New Black. Season 4 felt way too political and seemed to turn its characters into pawns to further a message.
There were some really strong scenes, but overall... I don't know. I feel like it could have been done better :/
