Absolutely awful, the positive reviews are mystifying

Rating: 3/10 (5 August 2018)

I can't quite believe how this film has earned such positive reviews from both audiences and critics. This has to be one of the dumbest, most boring and most unrewarding films I've watched in a long time. Nothing is ever explained, there are blatant inconsistencies and plot holes in the story, and the characters are all incredibly stupid and avoid doing what everybody else would consider common sense in this situation.
One of the things that annoyed me most about this film was the characters communicating in sign language. This makes no sense since the characters were making more noise simply by walking and moving around, taking stuff of shelves and so on, than they would have done by quietly whispering. Even when overlooking the plot holes, the film isn't at all scary and is tediously slow and dull. Clearly this whole concept wasn't thought through properly.
