I read Synder's The Black Mirror (Batman arc). It was okay, but it falls firmly into that Year One/The Dark Knight Returns genre of "serious" Batman books that don't really do much for me. The "villain," in particular, was rather bland. I get that's the point, but... I don't dig the Se7en style grimdark Batman stories. BEAUTIFUL art, though.
I also read the first 5 issues of Hickman's The Manhattan Projects. SUPER impressed. I was expecting some sort of wink-wink Atomic Robo series of historical jokeism from the description, but instead it's something much darker about America's relationship with science and the pursuit of knowledge at all costs.
