It takes place in a fantasy world somewhere between “Pirates of the Caribbean” and “Moby Dick.” The King and Queen have placed a bounty on sea monsters, enormous creatures that seem to be part whale, part octopus, part shark, and all scary. The kingdom’s most admired heroes are the hunters who kill the beasts and bring back proof to present to the royals.

Their adventures are legends. They and their fans believe that “Every hunter dies a great death because every hunter lives a great life!” A feisty young girl named Maisie Bramble (Zaris-Angel Hator) regales the other children at the orphanage by reading them exciting stories from old books (with engraving-style images evoking the classic era of illustration). She is determined to follow in the tradition of her parents, who died heroically on a ship called The Monarch. It is called The Inevitable, led by Captain Crow (Jared Harris), with his fearless second-in-command, Jacob (Karl Urban)

When Crow presents their latest trophy to the King and Queen, they are told their services are no longer required. The Navy will be taking over hunting duties. But Jacob persuades the King and Queen to give them one last chance. If they cannot kill the most feared beast of all, the Red Bluster, their ship will be decommissioned and they will no longer be able to pursue the sea beast, the central focus of their identity.

Maisie stows away on the Inevitable. She is not welcome. Jacob says, “The monsters I can handle. But that one will be the death of me.” Characters who are initially antagonistic will learn to understand and appreciate each other.

I liked “The Sea Beast” a lot and was never less than enthralled by the world it created. The animation and design are stunning, though there are a few disconnects in style. The ultra-reality of the water the ships are sailing on is so tactile you almost reach for a towel. The intricacy of the literally hundreds of ropes in the boat riggings are almost unfathomably complicated as they swing independently and get pulled, yanked, and unraveled. The kingdom and castle are brilliantly designed, both real and enchanting, with nautical touches emphasizing the connection to the water. The sense of space is exceptional, especially in the very dynamic action scenes. Jacob and the other hunters climb the masts as the boat is rocked by the waves and the monsters and every bit of it feels completely real. The movement of the human characters is not always as authentic and there is a character Maisie befriends who could be from a different, more stylized world.

“The Sea Beast,” like “Encanto” and “Frozen 2,” admirably grapples with themes of generational trauma and the stories we tell ourselves. When Jacob reads the book that has meant everything to Maisie, he is surprised to find the narrative inconsistent with his own experiences, amped up and one-sided and with characters saying “yar” much more often than happened in real life. It’s an ambitious film that almost completely lives up to its ambitions.

Parents should know that this movie has extended peril and action-style fantasy violence with characters injured and references to sad deaths. Characters drink alcohol.

Family discussion: How do you know whether to believe what you read or hear? Do you agree with the code? How did the characters decide who to trust? What do we learn from the name of the ship?
