A less Nazi-sounding Dexter, the boy genius of Nickolodeon has more realistic playground and family problems than the Cartoon Network version. But he still disagrees with Santa on a scientific basis. In his second season in ‘Holly Jolly Season’ he walks a million miles in the jolly old elf’s slippers to learn his lesson, but not before first suffering the indignities of grade school adulation for these ridiculous myths. “Basking in the Warmth of Christmas” is a jazzy show tune of faith vs. doubt.
