5.2? That seems extradinarily low for an entertaining, tense and decent budget Netflix movie. Ok, the first half is slow, admittedly, but from then on you have a very exciting and tense thriller, up there with Hollywood production quality. The story is basic, as one might expect with a thriller, but the characters are decently acted and the script is enough to keep your attention, without any boring bits. I would give this a 7.5, but as halfs aren't allowed, I bumped it up to an 8. It is worth a watch.
