Kairo or Pulse? Original or Remake?

With further researching during the past few days I have found another Japanese Horror Movie that has been remade for a mainstream audience. 'Kairo' a Japanese Horror movie which was directed by Kiyoshi Kurosawa was a big hit in Japanese but many critics could say that its American remake did not meet up to the standards of the original. The remake was calld 'Pulse' and it was released in 2006. It followed the same plot and had similar visual ideas as the original did. If I find a trailer for these films I will post them and you can compare the difference or similiarities of a western and non-western style of trailers.
