While I'm not a big fan of the twist ending, I do have to give credit for the effectiveness of the shock value. That legitimately caught me off guard and horrified me. Plus, everything preceding it was superb. Would've rated much higher if it had a different ending, but still a solid entry despite that.

wow, I had never seen a animation better visual effects

For some reason I guessed things were about to get dark with santa xD

Haha, nice. Good animation and incredible artwork. The dark and twisted ending was great, it actually surprised me and made me laugh.
