previews marathon

am watching previews of some movies and when the guy screams one of his eyes turns hollow and the other lights on fire!! and am thinking was that really necessary?! was it meant to be scary?! many times movies in an attempt to be different and unique end up being well unnecessary. i spoke too soon ave just seen another one where a human is fighting some not so human creatures and get this... they have two bodies but fused on just 2 legs...and, they are still spitting fire! whats up with that?! Finally the movie ave been waiting for "real steel".... its alive!
