i liked the second rd of rebirth books for the most part. aquaman was quite good i thought--little disappointing that manta is the big bad AGAIN, but seems like it could be solid. some good artwork.
i really like the way the ww book addressed her silly, convoluted history head on (aquaman did that as well) and looks to be ready to straighten some sh!t out. should be interesting to follow.
i liked action--the retro superman may turn out to be solid, though not sure how i feel about the whole 'family' thing. the appearance of another clark kent was intriguing though.
i also liked the flash book. that seems like it will be pretty solid as well. overall i gotta say i'm mostly enjoying the new stuff.
