The Japanese short (1 hr) horror films Ju-On: White Ghost/Ju: On Black Ghost were both released on 27th June 2009 to commemorate the tenth anniversary of the start of the Ju-On (Grudge) franchise. White Ghost was directed by Ryuta Miyake and Black Ghost by Mari Asato. Each film deals with the massacre of a family by what turns out to be supernatural means (the events of White Ghost are fleetingly referenced at the beginning of Black Ghost), but other than that they are unrelated to each other. And be warned - they are in that trademark Ju-On non-linear style of storytelling, so piecing together what happens can be a challenge if you fancy it (or just look at the Wikipedia entries for each film - they summarise the events for both chronologically).
White Ghost is easily the better of the two. The story's actually pretty deep, and deals with (amongst other things) the sexual abuse of a child. It also has a fantastic and gory third act and one of the creepiest openings ever for a haunted house movie (the cake delivery).
Black Ghost starts off well but never really achieves the level of creepiness of White Ghost. It also doesn't help that some of the adult female characters look so similar (it does, however, have the stunning Kana Tsugihara in a small role near the beginning).
White Ghost and Black Ghost both have some well-shot and atmospheric scenes, but White Ghost utilises them better - and has a much better payoff.
White Ghost -- 8/10, Black Ghost -- 6/10.
