“A House Of Dynamite” (** out of four) was an unexceptional political action melodrama about a deadly missile that’s fired at the U.S. and various political and law enforcement figures (Idris Elba, Rebecca Ferguson, Gabriel Basso, and others) race against the clock to find out who’s responsible and why and how they have to respond to save the country and stay alive. Surprisingly pedestrian outing from director Kathyrn Bigelow in what sounds like a sure-fire potboiler as she recycles various scenes and story elements from (the far superior) “Thirteen Days” and her own “Zero Dark Thirty.” Elba adds some style and panache with his effortless charisma but still can’t enliven this to actual “dynamite.”
