This is difficult to rate, because on one hand the film-making craft, vision and sound, is fantastic, but on the other hand the characters are morons, thus difficult to connect with. The male twice as dumb as the female. The decisions they make in the story are so thoughtless and stupid one can have little empathy or sympathy for them. They are 100% responsible for their own downfall.
There's some truth in this with the GPS. In the countryside we once had similar issues using GPS around the town of Trentham. The thing was making us go up dirt roads, driveways and so, completely ridiculous. They don't perform well out there. There's heaps of country-side in USA. They should have known this. And why didn't they have a real map as backup? This is just one of dozens of things they stuffed up on. I had no urge to want them to survive they were so brainless.
Why waste time making a film where there is no real challenge except from their own badly functioning brains?
