Oh dear what a shocker.
Too many bad things to mention in one post including unrealistic gravity, a stowaway who wasn’t a stowaway at all, but someone who somehow mistakenly got locked into a panel by his workmates and no one noticed and then there’s the CO2 scrubber!? Are we meant to believe that such a vital life supporting piece of equipment isn’t supplied in triplicate at least. Props were excellent hence 2 stars.
