You'd think that the poster boy for mid-90s 16-bit "tood" would have a better Xmas special than this! It seems that every animated hero from the 80s and 90s got to do their own "saving Xmas" story but this is probably the weakest effort I have seen from an established franchise.
Robotnik kidnaps Santa and plans to steal presents, and therefor Xmas, for himself. Sonic comes to the rescue, but not before earning super-speed which can make him zip around the world in no time and meet Santa's tight deadline.
This is generic, auto-pilot kiddie fare all the way. The muzak score is nothing but familiar holiday jingles with an overuse of "In the Hall of the Mountain King" (which isn't even an Xmas tune), the animation and locations are bland and forgettable, and the humor crass and slapstick. You're better off trying to appreciate the snowy atmosphere in the Ice Cap Zone in Sonic 3 and forget about this one.
