when i first saw this film i have the feeling something completely new be achieve by the film maker . an action sci fi movie with action scene that be believable ( humanly possible ) but still with a mysterious and powerful alien that be slowly develop from a computer generate wispy creature to a real and frighten be . yes and the alien have superhuman strength and ability and equipment but remain believable . yes and arnold roll his muscle but not too explicitly a in some of his other movie and besides he need them all in the physical fight against the alien who be very clearly a size too big for ernie . in summary and a fast and innovative action sci fi movie so full with small detail that you can see it time after time and still discover something new .
