No serious spoilers, but some very minor ones.

"Acacia", a Korean contribution to the ever popular Asian horror wave, concerns a husband and wife who decide that they're getting on a bit and decide to adopt a child. The child, who has an usual obsession with the dead tree in the family's garden, eventually disappears when the couple eventually have a child of their own and the aforementioned tree seems to hold a grudge against the family itself.

And that's about it. The film moves at a snails pace, clocking in at over 100 minutes with 80 minute material. It is essentially a thin family drama with a creepy tree, and there is very little in the way of scares, just shots of the tree with weird mumbling noises playing over the top. However, the idea of the tree being the child's mother is a pretty original one, but it isn't exactly exploited to its full potential. This sort of separates "Acacia" from much of the new wave it belongs to: films like Ju-On and Ring tend to do the opposite, and milk bland ideas until they are red in the face.

The film does begin to get going towards the end; however the realisation of the child's fate and the parent's actions not only dampen the earlier curiosity of the story, but are revealed with such machine gun editing that it's difficult to take in all at once. The final sequence is undoubtedly creepy, however it feels like too little too late.

Overall, the film does not feel too much like a Ring cash in, however with the "film renaissance" that Korea is currently going through, I couldn't help but feel this film could have been so much more.
