Don't mistake me for an Ebenezer; I mean no ill-will toward Frosty whatsoever. All I'm saying is that when it comes to choosing between the two, Rudolph guides my sleigh.
By no means is it perfect, and yes there are elements that haven't aged particularly well. It's just that when you compare the two, Rudolph the Red-Nosed Reindeer is a better Christmas Special than Frosty.
