Watching Carrey is an absolute delight; his comedic genius exudes more wattage than Sonic's moments of heated emotion -- and Sonic's outbursts cause power outages. Why did it take Hollywood so long to make Carrey a handlebar-mustachioed villain? His Dr. Robotnik is reminiscent of the over-the-top silly characters he famously created in movies like The Mask, Dumb and Dumber, and Ace Ventura: Pet Detective. Carrey's performance helps take Sonic the Hedgehog to levels of laughing you never expected. The best moment of all is when Robotnik does his Dance of Anarchy. Please, sir, may I have some more?
But as great as Carrey is, this is the story of Sonic, an animated alien hedgehog who's sent to Earth alone for his own safety. He's warned that if anyone sees him, they'll try to capture him for his special powers. So he settles in Green Hills, Montana, and watches those in the small town from the shadows with a wistfulness. Really, Sonic is like a little kid: He loves fart jokes, he can't keep quiet, he's (literally) bouncing off the walls, and he just wants a friend. It's a theme every kid can appreciate. Even if they don't relate to being alone, they can relate to being bored. As Tom, Marsden is a perfect companion to Sonic, popping off "dad jokes" and expressing his love for Olive Garden (the latter screams "product placement," but at least it's funny). The duo's evolving dynamic -- buddies, but really best friends, but really guardian and child, but really father and son -- make Sonic the Hedgehog a laugh-until-you-turn-blue fun film for the family to enjoy together.
