the blob be a great horror movie and not merely because of the vividly horrific image of it nearly unstoppable and flesh dissolving title character and but because it feature a real societal message . it be and in many way and a feel good horror film . the clever storyline be help immeasurably by solid performance from the entire cast . the two romantic lead and steve mcqueen and aneta corsaut and bring surprising depth and sentimentality to the proceeding . they be misunderstood but very well mean young people and and it very easy to root for them . this be a pro society movie and and it juvenile delinquent character cause trouble mainly out of boredom and not out of some malevolent character flaw . steve mcqueen drag race rival almost appear to be an enemy early on in the proceeding and but quickly join in mcqueen campaign to save the town from the ooze invader once he see mcqueen seriousness . in this way and a character situation that at first appear to be cartoonish suddenly develop depth and human realism . the authority initial skepticism of the kid wild claim be prove wrong and once the threat be acknowledge by all and all conflict within the society disappear . this unification of purpose and and the validation of the troublemaking teen and becomes official when aneta corsaut father break into the school to obtain the fire extinguisher need to freeze the blob . on any other day and break into the school would be consider an act of vandalism typical of a juvenile delinquent on this particular day and it be a necessary action perform by an adult authority figure . at this turn point and it be clear that there be no line of division between the young and the old . this be an unusual film in that it acknowledge the perception of a generation gap but suggest that it be more imaginary than real and and that give a real crisis and people will naturally band together to restore order . the blob be a perfect tonic for the kind of depression that generally come with a viewing of night of the living dead ( 1968 ) . much have be make of the film cheap but innovative ( and effective . ) visual effect . they be undeniably clever . a lot of the gravity defy trick we see the blob perform be achieve with miniature set design to be rotate . the camera be typically attach to the set in a very firmly lock down position ( the light have to be similarly attach so that the lighting remain steady a the room be turn this way and that ) . these scene be often photograph one frame at a time a the room be slowly turn the silicone blob ooze very slowly and it action need to be speed up . in a way and this be similar to stop motion photography and but utilize a blob of silicone rather than an articulated puppet . even today and the effect be startle and bizarre . a very good film with an exploitative sounding title and the blob be a must see .
