Abnett does a lot of smart, nuanced work in Aquaman Rebrith #1 that shouldn't be faulted for how uninventive the ending. Speaking of nuance, by the way, it's important to point out that Aquaman doesn't actually talk to fish. As Abnett notes early on, fish are too stupid to carry on a conversation. So, what Arthur actually does is control fish through a telepathic connection to them. The distinction is, perhaps, a small one, but if the issue strives to convey anything, it's that Aquaman is a good guy even if he's misunderstood. He deserves a little more respect.
