“Earthquake Underground” (** out of four) was a meager disaster thriller about a young architect (Matthew Gademske) who struggles to save his pregnant girlfriend (Angela Cole) after a massive earthquake submerges the hotel they are staying in and the city around them is collapsing. Strictly-by-the-numbers action movie made for disaster-movie addicts but the only intermittent visual effects and pedestrian dialogue will likely leave them as disinterested as everyone else. What is up with all of the nonstop disaster movies lately?
