After watching the American remake of Ju-On: The Grudge, I decided to go out and buy the 4 dvd set of the Ju-On series from Ebay.

I liked them. Though the very first movie is unnecessary if you watch the Ju-On 2. After watching the Japanese originals, I now understand whats going on in the American version, which is actually a pretty close remake. The story and things that take place in these movies actually stretches across all 4. In order to fully grasp what takes place in " The Grudge" , you have to watch Ju-On 1 & 2, and Ju-On: The Grudge 2. Just my 2 cents.
