Ancillary Justice by Ann Leckie (Orbit, 2013) Beneath layers of SF world-building (and guiding the reader to a gradual accord with such) lies a deceptively simple story, told in parallel via a past and a present plot strand. Integral questions of self-identity suffuse and sustain the slow-burning space opera.
Guardians of the Galaxy Vol. 2 dir. James Gunn (2017) Guardians manages to send up the superhero and space opera genres while still plying its trade within those realms (and benefiting from the associated conventions). The humour is patchy, all too often telegraphed yet proving very funny when out of the blue.
