It's really great and one of the rare ones that's great until the end, and it ends purposefully and well.

My only comment about it is the first handful of episodes are the weakest. After the first half of the first season they tone down the Joe MacMillan character to be less of a kind of over the top trope anti-hero and more of a real character with depth and things get better. They're not bad early on, but you'd probably notice that and it's worth watching anyway.
