This was good, but I didn't understand why it was a parody. It seemed pretty straightforward to me. There was nothing cynical about it. Granted, that's probably a good thing. I'm just so glad to listen to that song the whole way through. It was even nice seeing you at the end as well.
I'm so glad to be watching Christmas stuff this December! The animation in this could be better though. I guess it wasn't meant to be that good. Maybe that's why it's a parody? It's still a good cartoon.
