Pulse: Japanese vs. American versions

Honestly, I have never seen this movie, but I have seen the previews and I was not aware that there was a Japanese version of it. However, I am wanting to buy the movie as soon as I will be able to and will want to also check out the other version as well. Thank you for bringing that to my attention, I love Japanese movies!! Sometimes, I think they are much better than the American versions...LoL!! Have you ever seen the movie "The Eye 2"? That was a good one!!
