The beginning could have been more clear so audience could understand what was going on. How did the characters get where they were; and in their situation.

Not what I expected, excellent film, very well done, In the style of M. Night Shyamalan's Signs. The silence keeps you on the edge of your seat.8.1/10

Loved it!

A very good but scary, and also enjoyable for the whole family. Absolutely love Emily Blunt and her performance.
