IT IS either a very brave or foolhardy person who would take on the enormous task of making a sequel to one of the most iconic cult sci-fi films of all time.

But this follow-up Blade Runner is in safe hands. French-Canadian writer-director Denis Villeneuve, with the help of veteran cinematographer Roger A Deakins, delivers a worthy sequel which immerses us deeper into the dystopian universe created by Ridley Scott, who's a producer here.

Set 30 years after the end of the first film, the world is even more toxic both figuratively and literally. New blade runner LAPD officer K (Ryan Gosling makes the perfect replicant) uncovers a long-buried secret which could destroy what is left of society and it leads him to search for former LAPD blade runner Rick Deckard (Harrison Ford, who gives the film much needed energy and life) who's been missing for three decades.
