The premise of this scifi thriller is interesting and in tune with the times we are living in. I think the one major detail that would have rendered it truly modern would have been if the director and writer could hv avoided explaining the whys, the whos as is so often the case in USA movies where everything has to be explained away neatly. If they had left out the ‘explanation’ then the movie would have had a far stronger and lingering effect and in some ways been more believable.
