Why did they wreck it?

Rating: 7/10 (25 February 2019)

About 90% of the way through this movie I was thinking "this is probably one of the Top 5 I've ever seen". Then it ended. Probably the worst ending I've ever witnessed in a movie. All they had to do was cut to black after she went outside and took a deep breath. It could have been the perfect ending to one of the most intense movies. You never really knew if a twist was coming or not. Then, BOOM. From 10/10 to 7/10 because of the ending.
