Shutter starts with using the ghost appearance phenomena on photograph as the main theme, but as far as the movie goes, it reveals the plot regarding to long-lost love and bitter past life of the main character. i didn't expect too much from Shutter cause i thought it'd be another regular horror movie. (and it's from Thailand, which has produced some bad quality movie of this genre) At the end, i liked it. OK, it contains Asian-horror cliché, but the plot, the story and the puzzle are well-connected. not to mentioned the shocking sound effects and the superb conclusion. it's a big treat for Asian horror fans. very recommended (8/10)
