I watched The Name of the Rose last night (out this week on DVD) and spent a good deal of time squinting. While thematically a dark film, it's also visually dark. So much so you almost think you're watching something by David Fincher (Se7en, Fight Club, The Game etc.).
I realize a director wants to communicate certain elements (like theme) visually, but really ... is it a good idea to make a movie people can barely see? (Okay, so maybe it's not that dark.)
