This reviewer speaks from ignorance. When the Polar Express movie first came out, it was kind of a sleeper. Ticket sales were slow at first but as time went on, ticket sale kept growing and it was a very successful movie. Even Lionel wasn't sure how well it's sets would sell. They only made a limited number at first but the demand grew to the point where they had to make a second and third run. I can remember Polar Express sets selling on ebay for $800.00 the first year. Now, 20 years later, Lionel is still selling plenty of PE sets. My son has a tradition in his house. After the tree is up, he set up his Polar Express under it, then the family watches the movie.
