Its pretty funny, they claim they want more foot traffic in the place but then they never did anything like adding a few seating options in all this time to convince people to stay more than a few minutes. I really do like going in there. No, its not a huge priority but I usually stop in every time at night. But most people don't want to just stand watching the cartoons either, especially if you already been on your feet all day. More would come in if they knew you could sit and take some time to relax while watching. The Animation Studio in DCA figured this out years ago and added a lot more seating after the first few years it opened.
And if you wanted to sell something inside, fine, but keep it in line with the theme at least. Sell food items like bagged popcorn, drinks, candy, etc just like if you were going to to a real movie theater. Encourage people to buy something like that, give them a place to sit inside so they can eat it and watch. That's why people were so put off by it, it wasn't just because they were selling stuff inside, it was mostly the way it was done. It was rushed, crass and just completely out of theme.
Also for something so temporary.. they installed new lighting to light up the displays... which is now turned off...
