One of the most discussed aspects was the complete visual overhaul of Sonic after the initial trailer was criticized. The final version is widely considered charming and faithful to the source material.
The film follows Sonic, an extraterrestrial blue hedgehog with super speed, who teams up with a small-town sheriff (James Marsden) to evade the eccentric Dr. Robotnik (Jim Carrey) and the government.
Many reviewers highlighted Jim Carrey’s performance as a return to his energetic, 90s-era physical comedy, which provides most of the film's laughs.
