Is it predictable? Sure! Cliched? Absolutely! But there is nothing wrong with that if all you want is an full-on action flick.It follows the formula straight through - scientists on another planet get into trouble, in go the marines, who get picked off one by one until you have only THE MAN left and a girl. There's always a girl.It's this formula that makes Doom fun to watch - dont take it seriously and as always place bets as to who will be the first character to die a gory death.
