Prospect is a great hard science fiction story, one that could have come from Clarke or Asimov. It is both big and small in perfect proportion. It is big, because it gives us a constant and full sense of a much wider world than we seen in the film itself, without having to show us any of it. It is small because it is totally focused on the characters and their struggles, not special effects or spectacle. There is conflict and danger in abundance, because these particular people are in this particular place facing this particular problem. They are not trying to save the world, but rather just trying to survive.
They are Cee, a young girl stranded by circumstance on a hostile moon during a treasure-hunting expedition, and Ezra, a freebooter of dubious ethics, who is an enemy-turned-ally. Together, these two must face natural and human threats in order to secure passage back home - or at least off the planetoid full of threats.
The actors are wonderful. Young Sophie Thatcher gives a compelling, tightly-controlled performance as Cee - it's all in the eyes - while Pablo Pascal's turn as the expansive Ezra is captivating, seemingly an admixture of equal parts True Grit, Firefly, and Shakespeare.
As equally compelling as the leads is the art design. The vehicles and suits and equipment - excuse me, the sets and costumes and props - are all totally realistic and plausible in a retro-futuristic dieselpunk sort of way. Everything looks and feels utilitarian and grimy and used; I haven't had so strong a sense of realness to a science fiction setting since the first Alien.
If you want edge-of-your seat tension in a completely engaging sci-fi world, Prospect will not let you down.
