I rate this movie 8.5/10. Suspense-filled, fantastic, incredible plot-twisting "Screen Capture" movie. The movie is tense and so unpredictable kept me sitting on my couch from the first 10 minutes to the very end. Technology-savvy ones will really find the movie interesting, and realistic.
Reveals the power of privacy infringement through social media apps, mother's love, social media conspiracy judgements... The Internet is truly the world web, and understanding the usage is at another level.
PS:- A bird said, if you are over 45 years old and not in tune with modern technology, you may not like the movie.
