Really enjoyed this movie. Amazing performances by all actors, interesting storyline. Kept me at the edge of my seat and the story was not too predictable.
One thing I do have to point out though: the "Hey Siri", followed by a dramatic "call 911" line at the end kinda ruined it for me. Up until that point the dialogue felt authentic, but this little line suddenly made the whole movie feel like a 2-hour-long Apple advertisement.
