In its early chapters, Sunny read less like a conspiracy thriller and more like an exploration of grief and how our relationships with machines will evolve as those devices grow sophisticated enough to appear sentient.
Those ratios get scrambled in the series’ third installment, which offers confirmation that before his death, Suzie’s husband, Masa, was not merely involved in a corporate coverup of a robot-assisted (?) murder within ImaTech’s off-limits Division Five but was also consorting with the yakuza.
