OK I will start from how I started watching. Came on my prime suggestions, saw ratings and it was 7.8. So thought it will be superb and trust me the first half first season was indeed good.
But at the end of first season what promised to be a good show, turned worse from S2. Talking Talking Talking and nothing else. I have never completed watching 3 seasons in just 10days. Trust me I have fast forwarded so much yet didn't even miss anything.
There's no character development, story has nothing after s1, it's stretched till s3. And the s3 finale was worst.
My verdict, watch season 1 and last episode from s3. That's all it's worth. In between it's just talk talk talk and nothing.
