They fixed the way he looked, but does that mean Sonic the Hedgehog is a good movie? Directed by Jeff Fowler (in his feature directorial debut), Sonic the Hedgehog is the adventure comedy film based on the Sega video game franchise. Sonic the Hedgehog (Ben Schwartz) tries to navigate the complexities of life on Earth and teams up with local town sheriff named Tom (James Marsden) to escape the government and defeat the evil Dr. Robotnik (Jim Carrey), who wants to steal Sonic's powers for his robotics and probably world domination.
