Landing craft that all crash-land? Lake that freezes in seconds - physically impossible. Elemental magnesium in an oxygen rich atmosphere -- yeah right. Teenage girl stays calm while buried and immobilized -- 99.99% of adults would panic!. Besides, ice/melt is much better heat conductor that empty space - she would have frozen in minutes! All these impossible/improbable things happen within first 15 min of the show, and it doesn't get much better from then on. PS. don't get me started on annoying product placements, poorly written characters, repetitive dialogue etc///
