Yes, you know the plot. Yes, you know where the scary parts are supposed to be, Yes, you know the aliens' creepy abilities....yet...
The movie still scares and creeps the hell out of you. The Thing was very scary to me and i saw the 1982 version 10 times. The way everyone became suspicious of each other, especially when the 2 men came back from surviving the helicopter crash with... no scars.
This is an excellent movie for its category 'Alien Horror'. So if you want love story...get the Titantic, if you want horror...Get 'The Thing', I promise you that your girlfriend will be forced to hold your hand.
