But why tho ?

Rating: 8/10 (27 June 2018)

This is hands down one of the best thrillers I've seen this decade. The idea is solid, lack of a backstory adds perfect tension, the execution is brilliant and each actor does an outstanding job. Well worth watching if you haven't seen it. However,
SPOILERS:
The nail scene did not need to happen, that was just plain ridiculous, why, when the family are so meticulous around preemptive safety, would someone leave a nail in the middle of a safe tread area? Why would the mother drag the laundry sack instead of stepping back and unhooking it ? There was no point in introducing any of this because the next 5 mins would have produced plenty of noise without it.
Whoever wrote the scene for the last 5 minutes should have read the entire script first, the atmosphere for the whole movie was just plain grim, it was perfect for telling this type of story. To finish that with the mother pumping the shotgun like an 80's action hero kind of made everything feel cheap and lazy.
