I think that the video in the remake is so much better and they use it so much more in the film than the original, where it's just about four clips. The remake keeps your attention better, but the original has the scariest bits so much scarier than the remake, and jus bulks out the rest with slightly more boring stuff.
If you like the original the ring try 'Dark Water', another Japanese thriller, a slow starter but absolutely terrifying and so tension building it's unwatchable! So much more scary than the Ring
