I watched the trailer of the movie before deciding whether or not to give it a go and it intrigued me enough to watch. It is clear from the first few scenes that there are a few story lines going on here.
Filming wise I think it is directed well with some interesting shots and a soundtrack which certainly adds to heighten the suspense.
Horror wise I think that anything which includes figures with masks on is always scary and throughout the whole film it kept you guessing as to why they were there, the point and what the outcome might be.
I really felt that the whole way through it was tense and suspenseful as a true horror/thriller movie should be, my only disappointment came at the end where I felt the movie recycled and ending which is all to common in cinema today. It would have been so great for it to have been something different to carry on the feeling of the rest of the film, but this sadly was not the case.
It is still worth a watch.
