this be a pretty well know one so i would not get too deep into it . the basic story be about two teen who find out about a slimy alien blob of goo that arrive to earth via meteor . human contact with this slime ball burn through flesh like acid . it also absorb human body make it grow big . nobody believe the teen ( steeve mcqueen and his girlfriend ) and when they finally do it seem that the blob can not be stop . it really well do for it age and unlike a lot of other 50 flick the pace be pretty fast . the story be very unique make it and a must see for any fan of old sci fi and monster movie . if you can dig the gooey gore of 80 horror be sure to check out the remake from 88 as well .
