Loved it! An original take on the Christmas story - gorgeous animation, adorable characters and I loved how they relied on logic (not magic) throughout the movie to explain the "origins" of Christmas.
+ [Spoiler Alert] + I would've given it 4.5 stars if I could just because Jesper should've gotten silk sheets for Christmas. Also, they set it up perfectly for he and the teacher to take over as the next Mr and Mrs Klaus, to continue expanding the operation, but didn't take the opportunity.
