Decent premise, let down by the massively spurious plot holes and total lack of any research into any of the science/ medical/ survival/ radiation/ physics-related things that happen, and no knowledge whatsoever about how guns work.
Someone who has been tortured, would surely have lost lots of blood, and therefore be weakened and susceptible to sickness, is infected with a disease as a biological weapon and is, bizarrely, not the first person the disease kills? In fact, they don't die at all, even though others do. This is an infectious disease contained and stored by people who live in a forest, with no laboratory or means of identifying or storing a bio weapon. There's also radiation strong enough to horrifically mutate animals, but does nothing to the humans on the planet? Doesn't even make them infertile? Gravity on a space station?!? Someone firing a gun on full-auto for the first time ever and hitting targets a couple of hundred yards away?!? To name but a couple of many, many errors.
I imagine the programme wasn't written to target those with any knowledge of how physics or medicine work, but the writer could have at least looked things up on Google!
Also, the high explosive (fuel) found in the wreckage of a ship that exploded, and was actually part of what made the ship explode in the first place, but conveniently doesn't explode. Not. Enough. Facepalm. If you ignite a bowl of petrol, all the petrol burns. If you blow up a ship powered by highly explosive fuel, all the fuel explodes. Even more so if a single jar of it can cause the sort of explosion normally associated with 2,000lb bombs.
I'm aware it's science fiction, but the word "science" is part of the label. This has no grounding in science whatsoever.
