K-Horror night here at the Chateau.
First up was Phone (2002), Ghostly revenge/guilt story involving an astonishingly well acted child character in extreme peril. 3 hair balls.
The came Cello (2005) Ghostly revenge/guilt story involving astonishingly well acted child characters in extreme peril. 5 fingers.
Cello is by far and a way the best of the pair
It's really well made and a serious mind-funk but Phone was well worth a watch (the pre-title idents are fun, there is a Disney logo in Korean followed by a corporate animation for Toilet Pictures).
