Nicole Kidman, Patrick Wilson and Yahya Abdul-Mateen II reprise their roles in this follow-up to the 2018 blockbuster, which finds Aquaman balancing royal duties, fatherhood and unlikely reunions.

There’s a popular meme, spread across various social media platforms, where users upload a photo or video of themselves engaging in a series of increasingly ridiculous poses or actions. It’s accompanied by variations of the phrase “Never let them know your next move” — a cheeky imperative warning against predictability.  Unlike participants in this trend, the team behind Aquaman and the Lost Kingdom isn’t afraid of doing what’s expected. They seem to prefer it. 

I can recall a handful of impressively trippy shots, scenes filmed from angles that remind you that these heroes and villains are duking it out underwater. But for the most part Wan sticks to the video-game aesthetic of his first film. Rupert Gregson-Williams returns as composer and his score encourages audiences to feel emotions the story doesn’t actually inspire. Even the actors seem worn out by the ridiculousness of this sequel. 

When Arthur isn’t sleep-training his cherubic heir, he’s dozing off during council meetings or mediating in his constituents’ beefs. Through policy meetings and diaper changes, Momoa approaches his character with the same charming and goofy wit. Arthur might have the integrity worthy of the crown, but he’d much rather revel in the joys of fatherhood than keep the throne warm. 

Alas, duty calls. Aquaman’s nemesis, Black Manta (more Yahya Abdul-Mateen II, please!), still needs to avenge his father. In the last film, Aquaman destroyed the leather-clad villain’s suit with his mighty gold trident. So before Black Manta (who’s just David Kane when not wearing the insectile mask) can engage in another battle, he needs to fix his gear.

An expedition led by Dr. Shin (Randall Park) to find Atlantis-level technology to charge the suit leads Black Manta to the Black Trident. The weapon comes from an ancient Atlantis city, the Lost Kingdom in question, and there’s an entire story around it that’s gracelessly relayed too late in the film. What’s important to know is that whoever wields the spear makes a devilish pact. For the small price of their soul and eternal fealty, they can have their greatest dream fulfilled. 

With so much already on his plate, Aquaman knows he can’t save the world alone. Cue a fraternal reunion. Against weak protestations from everyone — including Nicole Kidman, returning as his mother — Aquaman teams up with Orm to save his family and the world. 

The pair set off on major adventures around the globe searching for ways to defeat Black Manta. Aquaman and the Lost Kingdom isn’t totally concerned with shaping a cohesive story so much as contriving situations for Arthur and Orm to bicker like children. The film seems to count on waning attention spans over its two hour run-time because as the story progresses so do questions about the narrative. Fiery power struggles are ignored and threads of seeming importance quietly abandoned. The brothers get into increasingly ridiculous situations. Some of them include imaginative renderings of ecosystems impacted by increased emissions, but most of the antics and their accompanying jokes are forgettable. 

What’s most disappointing are the stakes. Even as Momoa and Wilson leap, kick, fight, tease and save themselves and each other all the way to the Big Finale, the drama of their story stays at the same level. There are rarely any plot turns here when you really fear that Aquaman might fail or that his faith in Orm could be misplaced. I can recall just one moment in which I almost gasped.
