SiREN grows upon the mythology created in a segment in anthology film, V/H/S. The segment plays well at the beginning of the feature film and creates a deep mythology already and eludes to it as little as possible in its brief running-time. This time, director Gregg Bishop has a full feature-length to play with in his mythology, reinventing the world and bringing new characters with a similar dynamic to the segment itself. Amateur Night, the title of the segment, had promise for an expansion it seemed. Sadly, the feature film proves otherwise with all of the exhilaration and interest of the succinct short, evaporating as it lingers along.
