No characterization. A plot you could write on a single sheet of toilet paper. Sadistic violence we’re meant to cheer. A surprise that wouldn’t fool anyone who left the theater after the opening credits and came back for the last 10 minutes.
Following the last film's template, London Has Fallen has less villain appeal and strength, and the plot's far-fetched scope also turns the picture into a patriotic dream with American "Wolf Warrior"-like sensations.
