Overall, I'm liking BATMAN ETERNAL through three weeks:

Positives:  Snyder story/plot influence -- it reads like a well-paced novel with balance between exposition/action, coupled with an appropriate level of mystery
                  Jason Fabok's art -- I'm a fan
                  Love the urgency, consistency and payoff of a weekly story

Negative:  It suffers from a common Nu52 problem -- the reuse/reshuffling of familiar characters and plotlines.  It doesn't appear to be breaking interesting new ground yet.
