I liked the trailer more than the movie. I've been to the museum (Norsk Folkemuseum) in Oslo where this movie is at least partially made, the candy shop is part of the museum and also the town square is at the museum.
I recognized all the old style furniture that was typical in Norway in the 1960s. So I don't think it has much to do with IKEA from a content perspective - a comment about this was said in another review.
It's all a very typical Norwegian Christmas celebration, remembering some stuff from my own childhood even though I was not born back in the 1960s. It's based on a Norwegian children's book.
My 2-year old daughter liked the movie. She loves to hug anything she finds cosy, from fluffy sweaters to books showing teddy bears. My 5 year old son did not care so much about it he claimed, but still watched all of it.
The only moment of suspense for the kids was where a kid was in a situation of getting caught for illegal entry into a house...
My kids are not strong believers in Santa, not sure if kids become disbelievers by watching it. Santa never takes off his mask, but it's obvious to non-believers who he is :-).
The movie seems to be available at least with Russian audio, German and Norwegian.
