I am a completionist so I watched it all. I found myself very uninterested in any facet of the plot. Even the final scene I didn't particularly care what was going on. It is a beautifully shot show and the acting is fine, but it was time to go.
The plot just made no sense and the moments it touched on the current climate really had no impact.
Example. She acts crazy for 3 weeks making it seem like she has a reason, but then all she does is fire the entire cabinet, something she could have done at any time. Then she hires an all female cabinet which has about 5 second of relevance on screen and then means absolutely nothing the rest of the way.
She numerous times calls out how men have treated her and she's not going to take it anymore, yet nobody the entire season treats her a specific way because she is a female, rather it's all because she is a manipulative psycho.
I wish it would have ended with a bang and not a whimper, but oh well, it's done and it should be.
