Well, its plotline is awfully similar to the Jennifer Lawrence film, "The Boy Next Door", with the depressed girl and obsessive guy and all. The only difference is the "Hacking" part. I don't understand why films are taking this lightly. It's not something that you learn overnight. If it was possible that a19-year old guy could hack into a company system by himself, all those MNCs would be ancient history by now. It's not as easy as they show in the movies. It doesn't happen just because you will it. That was such a major turnoff for me. Apart from that, it was okay. It focuses on, or rather, tries to focus on the dark face of technology.
If you have got no reason to watch it, watch it for Rohan Shah, you guys. He is simply great!
