I saw a Japanese movie called Chakushin Ari when I was about eleven, a few months (as I recall) before this came out. Chakushin Ari is a j-horror about a cell phone curse-- you get a creepy and ominous call from yourself, foretelling your death, and it's not even your ringtone but a melody of death that plays. The killer is a little girl named Mimiko Mizunuma, a vengeful ghost (who suffers from asthma and her wheezing sounds are periodically heard behind the characters). One Missed Call has the same plot (it's a remake of Chakushin Ari), but there are some big differences that make it an epic fail. First of all, the character Mimiko was omitted from the plot and we have a different antagonist named Ellie Layton. They did a good job developing Mimiko's character and making her have that creepy vibe. Ellie, on the other hand, is not ghostly looking at all and is in fact probably the least scariest American horror movie villain I've ever seen. She's just a little girl in a black hoodie. I mean, seriously! The scariest part of the movie was the promotional poster (the lady on it terrified me greatly, actually... she's not a real character but just a ghost who appears in the beginning very briefly)! And in general, all the Chakushin Ari scenes are done a lot better. Anyhow, you should totally give Chakushin Ari a chance. It's a lot scarier.
