Honestly, if Trick 'r Treat is set up in the same format as Welcome to Silent Hill was, I honestly wouldn't be too upset. Given that The Shining takes place, for the majority of the movie/maze, in the Overlook Hotel, obviously black walls ruined that illusion. However, I'm fine with black walls for outdoor shots, as long as there are trees and shrubbery there, and considering how Silent Hill took you to different locations in the city, I would be fine if that format is repeated for Trick 'r Treat honestly.
