The idea is great and it has been explored before in other horror films but in different ways. The acting is actually quite good but gets repetitive from one particular actor namely the policeman. There's one fantastic scene in the second act (it involves a child) which was absolutely terrifying and deserves to be in the top 10 most shocking scenes in horror films. That alone deserves a proper watch. The final act was a bit of a let down as there was no explanations to certain events or occurrences therefore leaving one guessing what is happening. In fact, those 3 scientists/people of authority were totally useless in the film. At least one of them could've been useful but they were all sadly wasted in a plot hole. The very end was ok. But overall it's a worth a watch and good attempt.
