Re: Alan Grant/Norm Breyfogle Detective Comics era
I wouldn't be a monthly Batman fan if it wasn't for their Detective Comics run. The first half of their run is stronger than the latter when you factor in Batman and Shadow of the Bat but altogether it's still a bunch of solid reads.
I think their Batman run was underrated too. Definitely up there with Englehart/Rogers and O'Neil/Adams to me when you look at their best as a whole. Only Morrison has come close since in terms of consistency with the world building being done and how the storytelling is being pushed in crazy new ways.
