Some of my all time favorites are Ju-on : The Grudge by Takashi Shimizu and Ringu by Hideo Nakata. With films like Ju-on & Ringu it really just creeps me out and while films like Friday the 13th/Nightmare in ELM Street/Halloween gives me good scare. Ringu was the reason why I had to take the tv set out of my bedroom during college years while Ju-on made me think twice about hiding under the sheets LOL.
