"They say the book is always better, but who has time to read these days? With all due respect to the Edgar Allan Poes and Mary Shelleys of the world, the horror genre truly started to reach its full potential with the advent of film, when generations of campfire stories, shadow plays, and, yes, novels could be transformed into terrifying visual works that scald an imprint of their images into our brains. Plenty of great horror books have been adapted for the screen, but not all adaptations are created equal. Here are ten of our favorites.
For the book purists out there, it's worth noting that while some of these entries do compare the on-screen adaptations to their source material, we're not judging these films solely based on how they handled the material filmmakers and screenwriters were working with. Rather, this is a list of great horror movies based on books, regardless of how much may or may not have changed in translation during the adaptation."
