I just finished reading up to issue 17 of Injustice: Gods Among Us. The plot is just a rethread of Kingdom Come and Twilight of the Gods, but still has enough difference to merit a read-through.
One thing it has going for it is that it's a lot less melodramatic and philosophical than Kingdom Come. It doesn't take itself too seriously. It also features Aquaman proving how dangerous he and his Atlantean army can be. At least, for a while. Superman, Shazam, Wonder woman and Hal quickly shut him up by lifting Atlantis and dropping it in the middle of a desert.
It's also the first depiction of Harlequin that I liked. She always struck me as a fanservice character that has become the equivalent of a geek hashtag, but Injustice actually gave her some cool scenes including going all suicidal and trying to fight an angry/murder-death-killing Superman when she found out that the Joker was dead.
