The one I watched isn't dubbed as I understood what the characters were saying with English subtitle (and trust me it was well worth it). Don't let subtitle scare you away from watching an incredible movie. The trailers might be a bit off-putting, but trust me this story and characters would make your eyes glue to the situation right to the very end. Again, please don't be scare off by movies with subtitles, because you'll truly miss out on an excellent mystery/suspense/drama-filled movie. The mystery-crime novel has received awards and nominations both in the U.S. and Japan.
