Looking forward to trying out For All Mankind, See, Macbeth, and Invasion; the first two seem especially well liked by friends.
Bounced off Physical and Dickinson, but that had nothing to do with the quality of the shows; they're well made and have excellent acting.
The wide variety of stories and genres are lacking, but I think the quality of the average Apple TV+ show is quite a bit higher than the average Netflix show, on par with most of HBO.
