In his third feature-length go-round, Sonic (voiced by Ben Schwartz) and his blended family are faced with the menace of Shadow (voiced by Keanu Reeves) a hedgehog with powers augmented by military experiments-and loose after decades of captivity. The threat left Team Sonic having to strike an unlikely alliance with Dr. Robotnik (Jim Carrey) and his miserable granddad Gerald (Carrey, again). With James Marsden, Tika Sumpter, Krysten Ritter, and the voices of Idris Elba, Colleen OShaughnessey. 110 min. Widescreen; Soundtrack: English.
