This movie is very clastrphobic throughout the first like 5 or 3 minutes of the move you don't even know how He ended up being in there and I don't want to spoil anything.that if your a fan of clastrphobic movies this is definitely for you and I have seen a couple of Times already and I think that this is one of the most scariest film and most importantly clastrphobic movie that I've seen. I love this movie so much it is a great film
