The thing I keep coming back to with all of these pre-opening complaints is this: will any of it have a significant impact on your experience? The basic popcorn, the shading over the queue, the squares in the facade -- if you're hemming and hawing over all this trivial stuff (especially before the place is even open!), then it's hard not to feel like you're just going out of your way to find things to complain about. Just choosing to be upset over stuff that has little material impact on the success of this project.
Which, you know, it's an internet message board, that's kinda par for the course. But still. They're building a stinkin' Super Nintendo World. Who gives a crap about popcorn? It's popcorn.
