Let me say at the outset that I really enjoyed this film. I also don't want to give away any spoilers, but suffice it to say that almost every major plot point takes place because of or with the help of some Apple feature. Whether it be Live Photos, blue vs. Green texts, location tracking, they all play a part. If you are not familiar with these features, the much of the movie may go over your head. Even Siri gets to be the hero and save the day.
The movie is a missing person trope that relies on technology rather than violence and weaponry to move the plot along. Lies and misdirection keep you guessing, but it is technology that brings the truth to light.
