@Highland Laddie : he was talking about movies , not SciFi books . You surely need to read Stanislaw Lem , Frank Herbert , Arthur C. Clark , H.G. Wells , Asimov (in any order , plus some others) .
About the movies , yes i could also state that Starship Trooper (1) is one of my preferates , but still that depends on what are we talking about here . Is not an deep movie , is a pop-corn movie instead . I have some other preferate SF movies too , i'll just put them all on the same scale , none is the best and none is the worst .
