I genuinely enjoyed 90% of the film. The idea of having this young woman sleuthing through little more than the apps on her phone and laptop was quite well presented. So much so that, frankly, the scenes set outside that computer setting looked uninspired and slapdash, namely any of the cable news programming and police news conferences. The silly little things we all experience with the internet and social media were solidly, often amusingly, displayed (my favorite perhaps being the slight hesitation deciding whether a front edge of a bumper constitutes part of a yellow school bus in a CAPTCHA picture).
And sure, there are numerous plot holes, mainly due to trying to maintain the mystery (the who?, how?, why? Only come into question after the reveal). But all this can be ignored, as the movie was genuinely engrossing for the majority of the picture. Until... the reveal, which, no spoiler, is sadly predictable. And while I don't entirely object to the nature of the resolution itself, the movie oddly changes pace into a rather pedestrian imitation of an action-thriller. I really wish it had been able to maintain its core atmosphere, and not descend into the ordinary.
