The updated animation is not so updated that we lose the familiar characters. It does draw a lot on the situations I grew up on watching the numerous TV specials over the years, but it puts them in just enough of a new narrative that you just can't help but smile. Charlie Brown and his friends are timeless characters that will always be enjoyable.
I was so happy to see this episode of Dr. Who on sale as it was my favorite episode of the most recent season. Alex Kingston is great as River Song and her performance totally lit up what had been a dark and dreary season for the good Doctor.
