Agency just gets better and better through 6 episodes. I am a big fan, although I was a big fan of American Primeval right before that show drove itself off a cliff in the last 30 minutes of its final episode.
The Pitt is also good. It is most of the same creative team as ER from the 90's/00's. Think of it as "ER 2025" with everyone nicer and more respectful of each other than the original ER, and on streaming where the show can get a lot more graphic. I am not going to get hung up on the "each episode is a real time hour* structure of the show, which I feel is an unnecessary gimmick. Noah Wylie is a solid actor, but the rest of the cast are nobodies, which I don't love. There is one character that is pretty important where the actor feels a little weak.
