“The Lord of the Rings: The War of the Rohirrim” takes us back to Middle Earth, nearly 200 years before the adventures of the Bagginses and the Fellowship of the Ring. For those whose reaction to this IP brand extension is, “Great! I can’t wait to learn more about the stories behind the story and feel satisfaction when familiar places and characters are name-checked,” this animated story, produced by LOTR director Peter Jackson, will be welcome.

Fans of animation with a taste for anime style, are likely to find this a disappointment. While our heroine, Hèra (Gaia Wise) has big, sometimes expressive anime eyes, the overall style of the animation here is, in a year that included “The Wild Robot,” “Flow,” and “Inside Out 2,” disappointing. Many of the backgrounds are detailed and dimensional, some almost photographic, while the characters and animals are flat and minimalist. Their interactions with the environment seem weightless, any sense of heaviness or the impact of a punch or a fall coming more from the sound effects than the visuals.

Ancillary stories that spring like tree branches from beloved sources have to succeed as independent, stand-alone stories, and this one does not. The Lord of the Rings sagas, books and movies are memorable because of the compelling characters and storylines. The details of the world of hobbits, elves, orcs, ents, and a dragon, not to mention a complete language, are imaginative, but it is the themes of honor, purpose, and loyalty that make them beloved by generations. The characters and storylines here are close to generic.

King Helm Hammerhand of Rohan (Brian Cox of “Succession” and “Manhunter”) is a warrior by nature, physically and politically powerful ruler, generally fair-minded, though he underestimates his “wild, headstrong” daughter, Hèra in favor of his two sons. At a gathering of the noblemen, Freca (Shaun Dooley) barges in, demanding that Hèra marries his son Wulf (Luca Pasqualino) so they can take over the kingdom. Wulf and Hèra played together as children and she still feels warmly toward him. But she insists that she has no interest in marrying anyone. Helm and Freca get into a fistfight, and with one mighty punch Helm knocks Freca down, killing him. Helm banishes Wulf.

Wulf all but disappears and they hear nothing more from him for a few years until he returns, with an army, to capture Hèra and attack Rohan. This means a lot of battles, with just-passable animation and discussions of battle strategy with mostly passable dialogue. This movie never convinces us that there is a reason to make it, and that means there is only reason to watch it for those who will perk up at the mention of familiar places and characters.

Parents should know that this is a very violent film with many battle scenes and a few graphic and disturbing images including dead animals and a severed arm. A young man sees his father killed in a fight and a young woman sees her brother murdered. Characters are killed sacrificing themselves for others.

Family discussion: Why didn’t Helm listen to Hèra? Why were Wulf and Freca so angry and resentful? What was the scariest part?
