When I saw this film, I was genuinely scared by what was happening. The idea that you only had 7 days to live once you watched the video was chilling, and when I saw the girl climbing out of the TV and into the room, I literally felt my blood run cold.
Considering this is a remake of the original Japanese film, Ringu, it hasn't meant that it's of low quality, and in fact has retained all of the fright of the original. I highly recommend it!
