I must disagree with everybody who has written a review here ( 3 people to be precise ),and I will try to explain why it is like that.
First of all,to the all the people who have commented about this title I must ask a simple question: Did anyone of you ever watched more than two horror movies in your life?
So the movie is about old Chinese myth that turns out to be real and not a myth at all.The story is very simple and not very original.I have expected more of Eduardo Sanches since I liked ,,Altered,,.And to wait three years for something so average was certainly a disappointment.( Don't get me wrong,I don't think ,,altered,, the greatest movie of all time,but despite budget limitations and a few plot holes it was quite enjoyable and fun little b-movie).
The acting by Amy and Tim was OK,but my biggest problem was the look of moon demons( they were quite lame and ordinary in my opinion ).Some scenes at the end of the movie were a total ripoff of Descent by Neil Marshall.
Overall,this movie can be told in 2 minutes( I mean the story and everything that happens from the beginning to the end ).So the biggest problem of this movie is,like I said before,that it is so average it's painful.
While this certainly isn't the worst movie I have seen,it isn't the best one either.You won't be missing anything if you don't watch it,and if you do you'll say : Oh,well nothing special.
So since this is just an average movie I will give it an average grade 5 of 10.
P.S. Also for a horror movie,this flick isn't scary at all.
