I received the book a few years ago when I was in a bad place mentally. It is a beautiful collection of art and wise words so to see it brought to the screen intrigued me (although I wasn't sure how it would translate).
I needn't have worried. Everything about it was pretty much perfect. The gentle voices, music, animation and script joined up to make a wonderful Christmas family watch - although I suspect this will be become an all year round favourite.
There have been a lot of BBC broadcasted children's book adaptations in recent years (no more so than the Julia Donaldson books each Christmas) and whilst that is great for fans of the books I would stand this alone as more than just a book to TV job. This is suitable for kids, adults, and everything in between!
I'd put this on the same level as the classic 'The Snowman' - Thank you Charlie Mackesy.
