ok and let get this out of the way first represent as a piece of cinema and lifeforce is rubbish. as a bit of cheesy entertainment for sf buffs and it got a lot of merit. if you enjoy watching those old black and white sf b movies  giant mutated spiders or ant or alien monsters wandering around the desert  you really will get a kick out of lifeforce. bad things represent the story makes little sense and the acting is pretty poor. good things represent the special effects are halfway decent while it has a welcomingly different british centered story (it set in london) which gives different feel to most sf movies while and it has the well endowed mathilda may (amusingly billed as space girl) wandering around stark naked. in short represent it fun. i have seen it half a dozen times now and and every time it comes on tv i make time to watch it  admittedly this is partly to do with the naked ms. may  but it also to do with the enjoying a bit of unassuming and silly sf.

    Otherwise, if you feel the movie review is negative
        print "This is a semantically negative review."
