Deckard (Harrison Ford) is a retired Blade Runner, a group of elite people that have previously policed the earth looking for robots (known as replicants) that have returned following their expulsion some years before.
He is sent on a mission to annihilate four robots who hijacked a ship in order to return to earth to meet the man that manufactured them. Their motive is clear - as humans made the robots to have a four-year lifespan as a fail-safe against developing human emotions, they want this reversed so that they can live peacefully off earth for longer.
The storyline, from the beginning, is extremely difficult to follow. There are many, many reviews on IMDb about how people have hated this film on first viewing and then fully understood its purpose and moral standing on a second, third or fourth viewing. Unfortunately, I haven't had that luxury, so what will follow will be a controversial review to many.
It is possible to see a few elements of Alien in the landscaping and music work from this film and it is clear to see that director Ridley Scott was influenced with elements from his 1979 film. Unfortunately, unlike Alien it doesn't feel like anywhere near a completed work.
Despite a strong opening sequence, the film's many flaws start to creep in. Beginning with the setting - I can't imagine that even Ridley Scott himself thought that in 2019 (37 years after the film's release) humans would have developed robots with near-human emotions, let alone cars that fly and space travel so advanced it makes Neil Armstrong look like a caveman.
Deckard's emotional involvement with a replicant defies everything that the film teaches about robots and humans being so very different, and while this may seem to some like a clever method of developing the moral boundaries, it just feel like an absolute contradiction and a way of shoving a loosely put together love story in your face.
Overall, I may watch this film again to try and gain further understanding but for now... I'd rather re-watch Alien.
