Devs is just one huge plot hole. It generally doesn't make any sense. If you are willing to ignore that, you may be attracted by other, better aspects of the movie. It's visually beautiful, and script is made profesionally to pin you in front of the screen if you catch the emotions of it, but totally lame if we're taking about common logic. Don't mistake it with real sci-fi, it's just an average thriller with pseudo-science in the background, and idea that seems great at first but then it's falling apart.... *meh*
