They have all been really good, and they are creating a cohesive universe where you get more out of reading each title, without needing to read any of the other titles.
@John_Steed awesome! We are absolutely loving the new Valiant books. They are really, really great. Definitely let us know what you think after you jump in to the books!
From what I remember, the Batman/Catwoman relationship was severely downplayed after Hush, which was a shame, because it was my favorite part of that story.
I remember there being a "Heart of Hush" story arc at some point later, I don't remember the title or issues though.
In that pre-New52 continuity, I remember the Red Hood story arc being very good. It ran for a year or so in Batman, from what I remember it rolled out of Infinite Crisis, before Grant Morrison got his hands on Batman.
