The non linear plot really leaves you no time to be just chilling while watching this, but with a story so intense I don't think you'll be chilling anyways. It's like overdosing on caffeine while you have nothing to do so you just sit there feeling so edgy & tense. And not to mention the techno choice of score just seem to be adding more fuel to the tension.

During my viewing of this, I knocked over my soft drink and it spilled all over then I was bursting to pee but the story was super engaging that I can't afford a toilet break so I just hold off til the credits rolled.. C'MON!!
