Definition of achronological 

: not relating to, arranged in, or determined according to the order of time : not chronological As the achronological storytelling gimmick eventually becomes exhausted, the film's once off-beat energy fails to keep up until the very end, leaving viewers unsatisfied with its inauthentic, too-good-to-be-true ending.— Lauren Barbato, University Wire, 23 June 2009
