Why did people who obviously don't understand the charm of Anime or Manga decide to make an adaption of one? Take the Spiderman movie for example. Even if the makers weren't comic book fans, they understood the importance of keeping the flavor of the comic. Spiderman wasn't EXACTLY like the comic, but a real effort was made to stay true. Adaptations like this alienate the movie from its original fan base, and mangle the story so much that zero new fans are attracted. If this flops, you realize our chances for seeing other Anime live-action adaptations is very low.
