YMMV / Justice League: Throne of Atlantis

• Alternative Character Interpretation: Did Queen Atlanna ever really love Orm? Or did she always treat Orm as The Unfavorite who could never live up to whatever ideal his half brother Arthur/Aquaman represented to Atlanna, even though he wasn't even raised in Atlantis? Orm may be a Jerkass with entitlement issues, but Atlanna always comes across as being very cold and uncaring towards him. They spend much of their screen time arguing and while there's almost no dobut that Orm is not going to be the sympathetic character he was in the book, Atlanna herself never shows any real compassion towards him and never seems to make an effort to really understand him.
• Complete Monster: Black Manta readily assists Orm with his plan to start a war between Atlantis and the rest of the world, by slaughtering Atlantean civilians in sea craft that is disguised to look like a US military sub. Near the end of the film, Black Manta revealed he has been manipulating Orm into starting a genocidal war with the surface world, claiming that the war was his idea. Black Manta ultimately plans to kill Orm and take the riches of Atlantis for himself.
• Rescued from the Scrappy Heap: Superman, Wonder Woman, Green Lantern and even Shazam are considerably less obnoxious here than they were in War. It helps that Superman and Wonder Woman are portrayed closer to their default personalities than before.
• Fridge Brilliance: It makes total sense Hal is the one to stick Arthur with the "Aquaman" codename, which he hates. Hal's an Air Force pilot, and callsigns are chosen for you by your comrades, and tend to be unflattering or funny (to said comrades, anyway). "Aquaman" fills that bill nicely.
• Romantic Plot Tumor: The film spends part of its scant 70 minutes with Superman and Wonder Woman vs Superman and Lois Lane. The fact that both relationships have qualified as Fan-Preferred Couple and Official Couple gives the sequence a way to tick off fans as well.
• They Changed It, Now It Sucks!: Orm, who was a complex Anti-Villain in the original arc, being turned into a shallow, cackling Card-Carrying Big Bad.
• They Wasted a Perfectly Good Character: Due to Adaptation Distillation, a lot of backstory from the comics involving Mera, Black Manta, and Dr. Shin had to be cut. The circumstances of the death of Arthur's father are never explained, essentially negating the personal grudge between Aquaman and Black Manta.
