I wasn't too sure what to expect with this film. It is worth a watch, just once ! Not the type of film that you must see over & over.
I've always liked Sandra Bullock, it's a totally different of film type to her usual.
What I found missing from the story was after 5 years you still had no explanation as to what caused this phenomenon to happen ?
I will however, give it the thumbs up 👍as I did have to keep watching to the end I was willing them to survive.
