I, personally love this movie. Me, being a computer nerd and having some experience that kind of field, it really had me on the edge of my seat the whole time and made me felt uneasy. I really feel like the production team did their research when making this film, because some of the exploits the "hackers" used were real exploits that i knew and heard about. Although, with some elements of the webcams and the video glitchiness, that was more exaggerated. With how fast and broad technology and the internet is growing, things like what happened in the movie could very well happen to any of us, if we dabble in the wrong places. (Ive went through something similar, but alot more mild). Other than the okay acting, the actual effects in the movie were on point (mostly) with how they work in reality. Bravo in my opinion.
