Starts off well but goes rapidly downhill

Rating: 4/10 (14 July 2015)

As this movie begins we are asked to contemplate a world in which today's dire warnings of food shortage and unsustainability are proved to be correct. This is a gripping and sobering premise for setting up a post-apocalyptic scenario and engaged me for a while.
With hindsight, even at this early stage there were hints of the nonsense that was to follow. The high-speed chase, where a pick-up with a blown-out tire somehow manages to drive at top speed through cornfields without suffering any further damage, while Pop ensnares a semi-autonomous drone with his Dell laptop, is but the most glaring example.
As the movie wore on, it became increasingly confused and nonsensical. Getting to Saturn was vaguely within the realm of the credible. The description of why the wormhole was spherical was pure comic genius. The 2-D representation whipped up by our friend has a round hole, we are told, so the 3-D version must be spherical. But what if he had used a pen with a square cross-section to make his point? Would the wormhole have been cuboid?
Once they passed the wormhole, most principles of long-distance space travel seemed to be forgotten. The ability to hop from planet to planet, for some reason able to magically take off and leave orbit without the Saturn-V style craft or anti- gravity equations that would be required on earth, was nonsense. The plausibility of a habitable planet so close to a black hole seems dubious to me. And the final quasi-spooky drivel inside the black hole where some future humanity had gone to all that effort just to provide our hero with a totally lame-ass way of communicating... just sheer rubbish.
It could have been so much better.
