It's not a masterpiece nor it wants to be. It doesn't want to challenge our view of the world. It doesn't have political commentary at all. It is just a thriller of a disappeared girl and the desperation of its father, from the point of view of the father and the heavy influence of social media and internet in our lives.

Cho was good. Debra was ok. Some people found some wrong uses of technology (nitpick?). My problem was more about how the first and second acts have really slow/boring segments. But I don't think they damaged the movie at all. It is in fact a good movie, more than anything because of that great third act and the conclusion.
