There was a time and place for 2012’s “Iron Sky.” It was a nutty creation from director Timo Vuorensola, who mounted an elaborate fantasy with limited coin, placing focus on visual effects and a farcical plot that had Earthly forces encountering the wrath of Moon Nazis, leading to all-out war. It was cheeky, making fun of easy targets with help from its alternate timeline plot, and the helmer also enjoyed a chance to pants taboo subjects, including power plays from a space bound Third Reich. “Iron Sky” wasn’t sharp but it was amusing, a showy trifle made for cult movie appreciation. There was no need for a sequel, but nobody explained that to Vuorensola, who returns with “Iron Sky: The Coming Race,” which attempts to double down on absurdity and CGI while lacking a crucial sense of surprise. The follow-up is noisy and unfunny, still pawing at the same obvious political targets while expanding its capacity for mayhem, hoping to wow viewers instead of tickle them with relentless absurdity.
