The latest installment in the Sonic the Hedgehog franchise is a loud, mirthless, and confusing animated hybrid that fails to deliver on its promise. Starring Ben Schwartz as Sonic, Colleen O’Shaughnessey as Tails, and Idris Elba as Knuckles, the movie follows the blue hedgehog’s battle against an evil rival named Shadow, voiced by Keanu Reeves.
The film features a convoluted plot involving lasers, musical numbers, and a heist set in London. However, it lacks soul, wit, and any semblance of coherence. The humor is mostly internet meme-based, with characters talking like social media catchphrases. Despite its flaws, the movie’s commercial success is likely due to its familiarity and brand recognition.
Fans of the franchise may find some amusement in the film, but overall, Sonic the Hedgehog 3 falls short as a cinematic experience. With better animation and storytelling, this could have been a memorable addition to the series. Instead, it remains a mediocre corporate attempt at cashing in on the franchise’s success.
