Justice League: Throne of Atlantis (2015)
Dir. Ethan Spaulding
It surprised me to learn that Aquaman made his comic book debut in 1941. I'd not given his genesis any thought before now, but if asked I would've guessed that he was a product of the Silver Age. I don't know if the DC universe would be much worse off if he wasn't in it, but the modern (internet) age hasn't improved his profile much. The Throne of Atlantis movie doesn't help his credibility, either.
Before he dons the orange and green duds, he's dry-land dweller Arthur Curry (Matt Lanter). Arthur's father has recently died, leaving the young man lonely and angry as he moves through the stages of grief.
Besides loss and anger, the story explores yearning, belonging, belief, and teamwork, among other things, as Arthur uncovers his true heritage.
