Dark, bleak, and a very good supernatural film but I feel the American remake was by far the superior of the two!
Having watched The Ring series recently I am shocked by the remarkably huge differences between the two films! The remake had a menacing atmosphere of impending doom! Whereas this one just barely whispered I'm scary! The remake had far more details that I feel added significant pieces to the puzzle! The remake used visuals in disturbing ways to increase the horror factor!
Quite simply put it's a no brainer the remake is the winner!
With that being said... I feel if you are a true horror connoisseur then Ringu should also be included in your horror repertoire! After all it did inspire the making of The Ring! And is a fine film as well!
