‘Shaun the Sheep: The Beast of Mossy Bottom’ Is Already a Perfect Score on Rotten Tomatoes

Aardman Animation has spent decades proving that stop-motion charm never really goes out of style, and its Shaun the Sheep franchise has become one of the studio’s most reliable crowd-pleasers outside the Wallace & Gromit universe. The dialogue-free flock first made the jump to the big screen with 2015’s ‘Shaun the Sheep Movie,’ followed by 2019’s ‘A Shaun the Sheep Movie: Farmageddon,’ both of which built devoted followings well beyond the character’s original television roots.

Both prior films carried genuine awards pedigree too, with critics consistently praising the franchise’s blend of visual gags, dry British humor, and handcrafted charm. That track record set real expectations heading into the third installment, which trades the series’ usual gentle whimsy for something considerably spookier.

That gamble appears to have paid off in a big way. ‘Shaun the Sheep: The Beast of Mossy Bottom’ has landed a perfect 100% score on Rotten Tomatoes based on early reviews, a remarkable showing for a franchise entry attempting a genuine tonal departure from its predecessors. The film arrives in theaters September 18, running a lean one hour and twenty minutes.

The story finds the residents of Mossy Bottom Farm gearing up for their annual Halloween Hoedown when the clumsy Farmer accidentally destroys the flock’s prized pumpkin patch. Shaun responds by turning mad scientist, cooking up a growth serum meant to regrow the pumpkins, only for the formula to work far too well and send the farm spiraling into chaos, complete with a Farmer-turned-Sasquatch roaming the surrounding woods.

Early reviews have leaned heavily into praise for how confidently the film embraces its horror-movie framing without losing the franchise’s signature warmth. The Hollywood Reporter called it the series’ creepiest entry yet while still finding it every bit as delightful as its predecessors, going so far as to suggest it could easily become the third film in the franchise to land an Oscar nomination for best animated feature.

Other outlets zeroed in on just how thoroughly the film commits to its genre parody. Deep Focus Review noted that the movie packs in references to zombies, werewolves, and even the “Thriller” music video before the opening titles even finish, drawing direct comparisons to Aardman’s own ‘Wallace & Gromit: The Curse of the Were-Rabbit’ for its horror-inflected sensibility layered over classic slapstick.

Not every reaction has been entirely glowing, with a handful of reviewers noting that the film’s plot occasionally feels thin compared to its predecessors, functioning more as a loose clothesline for sight gags and topical humor than a tightly constructed narrative. Even those more mixed takes, however, have generally credited the film’s craftsmanship and comic timing as being on par with the rest of the franchise.

Directed once again by series veterans Steve Cox and Matthew Walker, with Justin Fletcher and John Sparkes both returning to voice the flock and Farmer respectively, ‘The Beast of Mossy Bottom’ looks set to extend Aardman’s winning streak just in time for spooky season. With reviews this strong out of the gate, the film enters its theatrical run as one of the more pleasant animated surprises of the year.

The film also leans into a small romantic subplot involving a local veterinarian who ends up hunting the very Sasquatch she doesn’t realize is actually the missing Farmer, adding an unexpected layer of sentiment to the otherwise gag-driven story. That kind of emotional undercurrent has become something of a franchise trademark, giving even the silliest entries a bit of heart beneath the visual comedy.

For families looking for a Halloween-adjacent movie that skews charming rather than genuinely frightening, the film’s early reception suggests it threads that needle about as well as anyone could hope. Between the perfect critical score and the franchise’s built-in goodwill, ‘The Beast of Mossy Bottom’ has a real chance to become a seasonal staple in its own right.
