Yes, the arm. I was pondering that, I just assumed that it made no sense because I'd spent the afternoon in a brewery. Seems not.
Vaguely entertaining, though the premise made no sense (the world having 'run out of energy' – how does that happen? – and then they pan down a line of running cars, everyone on their cell phones, and then they're using computers, etc. etc. and the solution is, erm, a supercollider in space, so I can suppose they were trying to make those special neutrinos).
I guess Netflix are into churning out enough movies to keep people subscribing, which is a quantity game.
Needed more monsters. We need a Cloverfield Cthulhu gig.
