Fan-frikking-tastic! This issue is probably even better than the last one.
Arthur is doing his best to impede the war between Atlantis and the surface which is proving to be quite difficult since the whole world is starting to fear Atlantis as much as Apokolips, for this reason he's forced to make action he usually would'nt commit. The problem is that Ocean Master is much more powerful than he ever was.
Sorry to repeat myself but I loved this issue. Johns dropped a lot of plot points for future stories here: T.O. Morrow, Red Tornado?, Will Magnus, The Metal Men, The Grid, Tula, etc. Everything helped to make the story much more compeeling and I have to say it feels like it has much more content than ever before.
The art is magnificent of course, I don't need to mention it. So far this crossover is delivering.
The Shazam backup was fun too.
