This Christmas episode is nowhere near as good as Woodland Critter Christmas but it is funny and has some great moments like Santa's "I couldn't do it, I couldn't let him live!" and Cartman desperately wanting to be nice.
The episode also brings back Kenny but makes little sense because the other boys act like they haven't seen him in a while even though half of season 6 had Kenny inside Cartman but making sense is something South Park usually try to steer away from anyway so it does have humour with it.
The fact that going to the North Pole, going to Jesus, saving Santa and escaping takes the same amount of time that Jimmy singing "The twelve days of Christmas" takes is very amusing but gets annoying aswell.
Overall, this is both funny and annoying but most of it is pretty good and is worth watching.
