I enjoyed it. It's not the best Batman story ever, and they might have overhyped it a bit, but compared to the whole Tom King's 85-issues-long run, this arc was a masterpiece.
I don't know how to define it, but it felt like a new style of Batman story, but it was still Batman. I think the AMAZING art of Jorge Jimenez really helped a lot to make it so popular. Jorge is literally the only reason I keep reading the Batman series.
