When i first saw this on VHS years ago, I enjoyed what would've happened if Christmas was in the Stone Age. The result is a great cartoon that has great music, decent animation, and a good plot, which centers on Fred Flinstone becoming Santa Claus, disappointing his boss at work. Along the way, Fred and Barney travel across the world and finally come home after getting lost in China. In the end, Fred thanks Santa for helping out and his boss decides to keep Fred's job. While not the first Flinstones Christmas themed cartoon (that honor goes to an xmas episode of The Flinstones), it's the best that Hanna Barbera has ever made.
