Well Season 4 is kindof a dud. Doesn't really feel cohesive in terms of storyline. There are great moments as usual but I think it tries to do too much actually and ended up not doing enough in terms of the big picture. Carmy brooding for ten episodes is exhausting and I guess it makes sense he needs to remove himself by the end. Syd is amazing as usual and a very well rounded believable character. Feels the supporting cast didn't get showcased enough this season. Carmy's unspoken, depressed, emotionless face eats up much of the run time in most episodes. Still an excellent quality show but feels like it peaked and they are unsure how to sustain the greatness.
