Oh dear oh dear. Monster alien runs amok on space craft. I can't say I'm disappointed though. There's nothing wrong with a bit of sci-fi schlock and it is very expensive, A-list cast well produced schlock, I only wish they'd been honest about it in the marketing rather than paint it as a sort of 2001 A Space Odyssey inspired 'deep' pondering on our place in this ether. It's a pile of goop running around a spaceship. Fun goop, mind.
