It's been a while since I watched a horror movie, and this Korean film is an excellent reintroduction to the genre.
A successful writer is caught up in a plagiarism scandal. Two years on, suffering from writer's block, she retreats to a villa in the country to concentrate on her writing. There her daughter talks about an imaginary friend who teaches her songs and stories. Suddenly, she starts writing, and before you know it she has a new best-seller.
Except that this, too, has been apparently plagiarised. A previous novel by a writer who stayed in the same villa tells the same story as her. Convinced that something weird is going on, she goes back to investigate.
I really enjoyed it. The use of remote location and creepy old house is hardly original, but don't worry about that. There are plenty of jumps and thrills, but it's all quite low-key. There's not a great deal of blood, although a couple of injuries will make you flinch. It's a nice story about uncovered secrets that some people would much prefer to keep secret.
