I'm a well read grad student who's bluntly honest about all things, although I try to be most honest about myself.
This is setup for the Rebirth series, which has to balance new readers like me, old readers, and actually set up the story. It does fantastically. It sets up the conflict between Atlantis, the surface world and the fact that Arthur Curry straddles the line: he's Atlantean on his mother's side, and human on his father's. He also happens to be the King of Atlantis.
He's known as a joke sometimes. The man who talks to fish. Less powerful than the rest of the Justice League. The truth is he's on the Justice League because he has more powers, and doesn't talk to fish. This series is quick to disabuse us of that notion. Fish aren't able to hold a conversation; he telepathically controls fish, and other sea life, to do his bidding. He is super strong, and has a will of steel. He's a powerhouse in his own right, and that doesn't even count his girlfriend Mera, who can control water, or his people - or as the US counts them a rogue state.
This series ratchets up the action by having an invisible party try to make the US, or the surface world, and Atlantis. When an extremist group of Atlanteans seem to take out a US ship, the US sees it as an act of war. The Justice League are forced to get involved: they can't have one of their own members allowing, much less condoning, this, and they can't even allow it to seem that way. Arthur Curry promises he'll go after the extremists, and disavows any knowledge of this, but it might not be enough. It makes him question if he can be part of the Justice League and King of Atlantis. And if he can call upon his friends in the Justice League in his time of need. He does everything he can to deescalate: he turns himself in, to be imprisoned until everyone is comfortable he's not to blame, and when an officer offers to uncut him, he points out he could have done that himself. No, he'll allow himself to stay cuffed so that it's clear he's being cooperative.
By the way, Arthur takes a punch from Superman and Mera hits big blue right back. Neither of them are lightweights by any means. This is due to Atlantis' distrust of the surface world: no one is comfortable with Curry in cuffs, and more than that, they need him to lead Atlantis and also to find out who's really at fault for the sinking of the ship. He doesn't see it that way and insists that Mera made things worse by breaking him out, although she will never agree.
Plenty of action, plenty of friction between the characters, and I'm hooked.
