Although Polar Express (PE) is not something I am inclined to purchase for myself, I would love to go on a PE ride with my wife, adult daughter and granddaughters, and think Lionel PE trains are wonderful for children and others who find them appealing.
Another very good thing is that I understand PE Trains have been very profitable for Lionel, and I believe that is very good for the hobby. It enables Lionel to have more financial resources to manufacture the models that I prefer to purchase.
