The original Japanese one. I was a bit disappointed by this, i thought it would be way better, but it's still a little bit better than the mediocre american version. Basically nothing of interest seems to happen during the first hour of this film even though there's a weird and creepy vibe, it's not until the last half-hour or so that it actually turns into something tense and interesting. The part where Sadako crawls out of the tv near the end and kills Ryuji is as creepy as f*ck though.
