I watched this film this week and was kind of disappointed by it. It features 3 very beautiful women in Thailand who are there to teach English but as soon as they reach their accommodation in the middle of nowhere they come under the spell of an evil spirit. The supernatural element of the film actually misses the horror spot entirely in my view. There is a visit to a witch, which is the least spookiest witch scene I have ever seen. There are some scenes of gore when the women bring some British guys back to their house but even these are a disappointment. Overall, it's largely a missed opportunity to do something original. I wouldn't be surprised to hear that it was an American remake of a genuinely scary Japanese horror film. I can't recommend Pernicious to audiences of either gore films or supernatural films.
