What a great issue, really seeing the long term relationships and character development, Batman and Superman are friends.
What is really touching is the humanity of Superman and Wonder Woman. Johns is really stressing how humane these superhuman people are.
The extent to which Superman is shown needing Diana was deftly done. It was imeediately clear how much he admired her honesty and compassion. The scene of visiting Smallville completely turned upside down the tradtional superhero date trope, ie don't reveal your Secret ID, or your past, and don't appear in public with your significant other.
That was such trope subversion I lol'd.
That Clark opened up so completely to Diana - without the tradition deception and lies was fun.
The scene where Clark tells her it's her compassion, her never ending battle for truth and justice inspires him was both simple and compelling - He has the legacy of his late parents values, she arrived choosing the same mission herself.
In short Superman's need for Diana was convincingly SHOWN in his choice of taking her home and revealing himself. Here I am he's saying him showing Diana his beginnings.
Diana needs were more told - she needed to be reminded that her natural instincts were good despite the Cheetah episode, which was well done in terms of sharing the fight, and turning up the Cheetah as villain, although the Superman as a werecheetah was fixed a little easily. Aquaman was of course very useful. It was more a obvious by the numbers use of the narrative ie being told why Diana needs Superman by these events.
This was somewhat emeliorated by the Art, and the use of eye shots which told us that Diana is attracted to Clark.
The only thing that really cracked me up was that Bruce watching Diana and Kal at the end is pretty much exactly the story in Yale Stewarts brilliant JL8.
