The first moment of stupidity I noticed was when the main character was testing stagnant puddles for chemicals and life forms. She said she has found a bacteria that is using ammonium as an oxygen source. Not possible. Ammonium is not oxygen and never will be. I understand what the writer meant but, who wrote this script, a tenth grader that hasn’t cracked the binding on a thesaurus? Secondly this chick got on her four wheeler and started speeding down the road in this oxygenless planet. Internal combustion engines require three things to run and this planet was supposedly lacking oxygen. This was ten minutes in. This movie should get negative stars for insulting the audience.
