The Witcher: Sea of Sirens Review – Stunning Action, But Lacking Depth

Netflix continues to expand The Witcher universe with the release of The Witcher: Sea of Sirens, a second animated spin-off that explores the world of Geralt of Rivia and his allies. This installment is set in a coastal kingdom where tensions between humans and merfolk reach a boiling point, offering a rich setting for drama, intense action, and complex moral choices.

While the film excels in delivering visually striking underwater sequences and dynamic combat scenes, it falls short in crafting a narrative with the depth typically associated with the franchise’s source material.

What is The Witcher: Sea of Sirens About?

The Witcher: Sea of Sirens adapts Andrzej Sapkowski’s short story “A Little Sacrifice” from The Last Wish, the second book in the saga. The story is set between episodes 5 and 6 of the first season of Netflix’s live-action series and follows Geralt and Jaskier as they travel to the seaside duchy of Bremervoord.

Their mission is to hunt a sea monster terrorizing pearl divers. Along the way, they encounter Eithne Daven, a poetess, and become entangled in the tragic love story of Prince Agloval and the mermaid Sh’eenaz.

Although the adaptation retains some core elements of the original tale, it introduces several creative deviations. For instance, Agloval is portrayed as a young prince rather than a greedy duke, and his relationship with Sh’eenaz is given a more romantic tone. Additionally, Lambert's backstory is explored, revealing his childhood connection to Bremervoord and how Eithne once protected him from bullies.

Art Style and Animation

Once again, Studio Mir—known for their work on The Witcher: Nightmare of the Wolf—brings its distinct artistic flair to this project. The animation truly shines in its depiction of the underwater world. The merfolk are intricately designed, blending traditional aquatic features with subtle dryad-like aesthetics, which sets them apart from typical fantasy portrayals.

These characters also speak a unique dialect of Elder Speech, reinforcing their cultural divide from humans and adding emotional weight to their forbidden romance with Agloval.

However, while the visuals impress, there are moments where character designs feel inconsistent compared to the live-action series. Geralt, voiced by Doug Cockle instead of Henry Cavill, maintains much of his rugged appeal, but other characters don’t receive the same level of attention. Eithne, for example, lacks the allure described in the books or seen in earlier adaptations.

Action Sequences: Visually Impressive but Flawed

One of the film’s strongest aspects is its high-energy fight sequences. Geralt’s battles are packed with sword clashes, acrobatics, and magical effects that bring excitement to the screen. However, these action scenes often prioritize spectacle over realism.

Geralt appears to use signs without clear reasoning, drinks potions mid-combat without explanation, and performs moves that defy logic. Longtime fans may find this portrayal unsatisfying, as it diminishes one of the franchise’s most iconic figures into a generic action hero.

Moreover, the choreography leans toward superhero tropes, which contrasts with the grounded nature of Geralt’s fighting style seen in the games and novels. Despite these issues, the intensity and brutal nature of the fights make them entertaining, even if not entirely fulfilling.

Storyline: A Mixed Bag

Unfortunately, the narrative struggles under the weight of its ambitions. While Sea of Sirens attempts to tackle themes like interspecies conflict, tragic romance, and Geralt’s internal dilemmas, it ultimately feels disjointed.

Key plot points rely too heavily on predictable clichés, such as an Ursula-inspired villain reminiscent of Disney’s The Little Mermaid. At times, the tone shifts abruptly, briefly turning the dark fantasy into a musical sequence that feels out of place.

Eithne’s character arc is particularly underdeveloped. As a renowned bard and potential love interest for Geralt, she should have been compelling. Instead, her performance comes across as flat, failing to capitalize on Joey Batey’s charisma as Lambert. Meanwhile, Geralt’s moral conflicts remain superficial, offering little insight beyond surface-level reactions.

Comparison to Previous Adaptations

Compared to Nightmare of the Wolf, Sea of Sirens falls short both narratively and emotionally. While the former focused on Vesemir’s origin story with depth and emotional resonance, the latter feels scattered and overly reliant on visual spectacle.

That said, the underwater sequences and vibrant animation elevate Sea of Sirens above mediocrity, offering enough visual appeal to justify a watch.

Behind-the-Scenes Insights

Bringing Sea of Sirens to life involved close collaboration between Netflix and Studio Mir. The production team faced the challenge of staying true to Sapkowski’s writing while meeting the demands of modern animation.

According to interviews with animators, designing the merfolk was particularly difficult due to their dual nature—both beautiful and dangerous. To capture this balance, artists drew inspiration from various mythologies, including Greek sirens and Slavic water spirits.

Fan Reactions and Criticism

Fan reception has been mixed. Some praised the effort to adapt lesser-known stories and appreciated the visual creativity on display.

Others criticized the liberties taken with established characters, especially Geralt’s erratic behavior during combat. On social media, many fans expressed disappointment with Eithne’s portrayal, questioning why her role wasn’t developed further.

Future Prospects for Witcher Media

With Sea of Sirens now part of the official canon, questions arise about future projects in The Witcher universe. Will Netflix continue exploring side stories through animated films, or refocus efforts on the main live-action series?

Given the franchise’s popularity and past successes, more content seems inevitable. Fans eagerly await news about possible sequels or spin-offs centered around characters like Ciri or Triss Merigold.

Broader Implications for Fantasy Franchises

The Witcher: Sea of Sirens highlights broader trends in adapting literary works for screen. Balancing creative freedom with fidelity to the source material remains a delicate task, especially for beloved universes. Studios must navigate carefully to avoid alienating long-time fans while still appealing to new audiences.

In this context, Sea of Sirens serves as both a success and a cautionary tale. It showcases what can be achieved visually and thematically, while also exposing the risks of losing narrative depth in the process.

By learning from its strengths and weaknesses, creators can refine their approach for future projects, ensuring richer storytelling and more authentic representations of cherished worlds.

As The Witcher saga continues to grow, so does its influence on popular culture. Each new installment contributes to the evolving tapestry of fantasy storytelling, proving that even imperfect adaptations can hold value within a larger narrative universe.

Should You Watch It?

For die-hard fans of The Witcher universe or those curious about Studio Mir’s interpretation of Sapkowski’s work, Sea of Sirens offers a worthwhile visual experience. Its stunning underwater visuals and partial adherence to “A Little Sacrifice” provide glimpses of brilliance.

However, viewers expecting a cohesive storyline or deeper exploration of beloved characters may find themselves disappointed.

Ultimately, The Witcher: Sea of Sirens is best viewed as a curiosity—an
