The International Thriller Writers (ITW) characterizes a thriller as «the sudden rush of emotions, the excitement, sense of suspense, apprehension, and exhilaration that drive the narrative, sometimes subtly with peaks and lulls, sometimes at
a constant breakneck pace.»
The absence of true danger and, thus, suspense, proves a
constant narrative obstacle, though it's nonetheless one occasionally hurdled courtesy of
breakneck pacing and clean choreography that's first evident during a slam - bang opening chase, and regularly picks up again during similar sequences in which its characters race through streets, leap between apartment buildings, and sneakily infiltrate a crowded police station.
