I have recently seen this film and as a scary movie it is very solid. The plot is sometimes confusing but the shocks are genuine and will have you hiding under your sofa several times. The horror element relies on shocks and make-up effects as opposed to loads of gore and CGI (however there is a smattering of this). Defenitely one of the best Asian horror films since 'The Eye' and would be difficult to keep its authenticity if remade in America. The music is atmospheric, reminiscent of the Resident Evil Games and adds to the tension running through the film. I am still unsure to why the boy, mother and father haunt/kill anyone entering the house.....wasn't really explained very well but leave your critical reasoning aside when watching it and enjoy the production for what it is a roller-coaster ride of jumps and scares.
