I liked it. Even though I thought I would not, but I say it again, I liked Superheavy. Commissioner Gordon as the new Batman was a tough thing to accept at first, but once you get over that, evrything falls in place as an entertaining Batman story. 
 It is just that Scott Snyder has consistenly delivered great Batman stories eversince the first issue of his New 52 run that Superheavy felt inferior. In some sense, there is truth there, but this volume is not really aiming for greatness, it tries to be relatively more fun and energetic. Gordon Batman is not Wayne Batman, and I respect how Snyder treats the story with a lighter mood. Even Gordon himself facetiously shows this with his utter dislike with this idea of being the Batman. His meta-comments about how he hated this idea made me laugh! 
 The villain Mr. Bloom is interesting, though he did not feel unique. Batman's rogue gallery is a mixed bunch of interesting characters, but Mr. Bloom doesn't fit very naturally in the group. I mean he is interesting, but it really felt that he is not someone we did not see before. 
 There was one issue (44) that is very different from the rest of the issues in the volume. Although it was in fact a great read, putting that in a collected edition kind of disrupts the continuity of the whole story.
