One of my all time favorite scifi/horror movies. I saw in the theaters when i was young and it terrified the hell out of me!
The whole setting is wonderful and the monster is chilling and I loved the paranoid atmosphere.
I am a huge fan of the 50's Thing from another world too for different reasons (I love Howard Hawkes style of directing and the witty banter from his characters) In its own way it scared me too as a kid.
Something about the cold isolated enviroment has always been a favorite of mine too.
Now I feel the need to go pop in BOTH of those DvD's tonight. lol My wife is gonna kill me
