The eyeball alien once again steals the show. Equal parts creepy and weirdly cute, it even has a moment of charm when it tries to warn Science Officer Chibuzo (Karen Aldridge) of imminent danger. Then, of course, it commits perhaps the grimmest act ever involving a water bottle on television. I found myself rooting for the little thing - until it started drilling into eye sockets with Spider-Man-like agility.
From there, the carnage escalates. Each crewmember dies in a more gruesome way than the last. We even get a triple kill from one species - Mum, get the camera! Bloodsucking, lung-lining, oesophagus-latching bugs? Check. An eyeball critter darting around like Spidey and burrowing into skulls like an evil Usyk? Yup. A feral Xenomorph variant so vicious the UK Government would ban it? Absolutely. The episode is a gory joyride, full of surprises, and the practical suit work - though clearly a bloke in a suit - makes it all the more fun to watch.
