The film asks all the right questions.

For example, can you empathise with replicants as much you can with a human? What about Ryan Gosling? Set aside the small technical point that the replicants are bio-engineered rather than robotic in the Ex Machina sense. Blade Runner 2049 successfully blurs the edges between mankind and manmade. It seems like a good idea to design a non-human slave class. But, what if the replicants become too like us? Indeed, the replicant enforcer, Luv, cries as she kills. It does not stop her killing but the emotional neural circuits are clearly there. It’s all accompanied by a convincing plot, fabulous scenery and a doom-laden sound track.
