Its interesting, recently I have wondered how hard it can be to merchandise some serious adult superhero films for kids. Nolan's Batman films for example. I look at the kids books at Wal-mart and Target. They avoid the more adult elements, like Batman defeated by Bane, and really just introduce the characters in broad strokes.
None of that compares to this! Which made no effort to gear it towards the age group of a coloring book!
