I couldn't stop thinking about sunscreen during the first two minutes of "Beyond the Reach." After 15 minutes I was trying to conjure up images of polar ice caps and northern lights. This is what happens when fragile people like me are overexposed to UV rays, even when they are cinematic. The sight of bone-dry water containers on film make me panic, so after a little flailing, all I wanted to do was crawl out of the theater to find the nearest drinks machine.
