Trust me, yes, they were better, even in the case of Moontrap which was otherwise a really bad movie.Biochem - which direction is the energy flow between converting carbon and oxygen to CO versus the opposite? (Or in other words changing CO2 into oxygen and carbon requires energy, creating CO2 from carbon and oxygen releases (not creates) energy. It is easier to burn than to 'unburn'.)Noise in space.The names given the little green hoppy things was not even in the right family. Where did the mass come from?This is alll highschool science...Did you bother watching any of these with an eye to science, or did you just like them all about the same?The Auld Grump, who wants to be rather snippy about this, but will stop here...*EDIT* I should mention that it is lack of notice that folks in general have toward basic physics that has me snippy, not any person in particular.In the movie Contact (and the book as well) there was a distinct ambivelance as to whether what she perceived was what happened. In both Moontrap and the 2001 movies there was no sound in space and in Moontrap the hero used a submachine gun as a reaction drive to push himself back to the ship. (In Mission to Mars the nit wit could have saved himself by throwing something away from the ship pushing him back towards it.)</blockquote>
