Jon and Skull – Matthew to his mum – are men with a passion for technology and built a business around that. They also embrace anything innovative, as John Jon has embraced Lucy; a smartphone app that monitors and assists with his health and life choices. Skull is more into the idea of expanding Tesla car technology and so lets Jon get on with it. Therefore when Jon goes missing, Skull is not only surprised but doesn't realise what Jon was caught up in. Shame he didn't pay more attention as that would not only help Skull find Jon, it may keep both of them alive.
For me the best sci-fi takes that which is around already and simply extrapolates. This is precisely what Joel's done by taking us further into the world of that little app-saturated ringing thing in our back pockets and bags. Extending its artificial intelligence and ability to interface with other programs, Joel gives us an idea of the near future in an almost earthbound ''2001'' direction.
