Screenwriters John Glenn, Jacob Roman, and Kenny Ryan create an unusual alien invasion story for “Elevation.” Creatures emerge from the depths of the Earth and clear out 95% of the world’s population, and it’s impossible to kill them due to impenetrable scales and swift movements. The only thing they can’t do is move above 8,000 feet, pushing survivors into the mountains, creating a new way of life. There’s a decent hook with “Elevation,” which supplies a few different locations when depicting creature rampages, allowing director George Nolfi (“The Banker,” “The Adjustment Bureau”) to stage some passably intense screen action. The rest of the feature is less confident, stumbling through clumsy dialogue exchanges and dealing with a grand franchise plan that requires the first film in the series to grab viewer imagination. And that doesn’t happen so easily in the endeavor. Read the rest at Blu-ray.com
