Considering this was placed on the live show for Rifftrax's Christmas shorts, it probably was the one with quality work put into it, at least compared to the others. There are certainly things that can be mocked about it, moments like when Santa Claus is literally patting the reindeer one after the other on the butts as they go out the door, or in some of the unintentional innuendo between Rudolph and Santa as the latter drafts the former to help him on his sleigh ride Christmas eve. But there is decent enough animation that makes it watchable outside of seeing it 'riffed', and I realized I actually had seen it before, at least at some point in my life, before seeing it here (why it didn't stand out exactly... well, it's not in stop motion for one thing). It's corny and cheesy, but for its time it's fine.
