When the manic Dr Robotnik returns to Earth with a new ally, Knuckles the Echidna, Sonic and his new friend Tails is all that stands in their way. Action,Adventure,Comedy The first Sonic movie was surprisingly competent. This one is even better, incorporating additional elements from the games and sticking to more of an action-adventure plot. It's a kid's movie through and through (way more toilet humor this go-around), but a fun one that never takes itself too seriously. Everyone in my theater was having a great time with it. As with the original, Jim Carrey steals the show as Eggman. This man is 60 years old and yet he has more verve than I do! He's so energetic he sometimes resembles a cartoon more than Sonic, Knuckles, or Tails! While I respect his desire to retire, I do hope he holds on and does the third movie-- there would be such a void without him there.
