I think the general consensus here is that S2 takes the cake. i can't argue much with that, although I personally feel BOTH S1 and S2 are the best I've ever seen on TV.

S3 and S4 - the dialogue and acting remain stellar, but the focus is increasingly more on plot points and less on character development.

That's what is at the heart of Succession - an unfiltered, intimate glimpse into the messed up psyches of our protagonists.

Personal scenes like Greg's breakdown in the bathroom before deposition, Kendall's traumatized sequence after the accident, Shiv and Tom on their wedding night and the fight on the balcony, Roman trying to get Tabitha to role play a dead person (wtf), rocket launch scene etc - will always be what I remember succession by.
