Sonic, Knuckles, and Tails reunite against a powerful new adversary, Shadow, a mysterious villain with powers unlike anything they have faced before. With their abilities outmatched in every way, Team Sonic must seek out an unlikely alliance in hopes of stopping Shadow and protecting the planet.

With a double helping of Jim Carrey's antics and a quicksilver pace befitting its hero, Sonic the Hedgehog 3 is the best entry in this amiable series yet.

Adults beware: Sonic the Hedgehog 3 has enough charisma, laughs and thrills to get you -- err, the kids -- excited for the next installment that will hopefully arrive at Sonic speed.

'Sonic the Hedgehog 3' offers thrilling action, humor, and emotional depth. Keanu Reeves as Shadow and Jim Carrey's dual role are praised. Visual effects and CGI are lauded, but pacing and humor are criticized. Core cast performances are strong, though some characters are underutilized. The story is engaging yet predictable, with fan service. Action sequences and soundtrack are highlights, but Shadow's backstory and human characters are disappointing. It's a fun, action-packed film with room for improvement.
