i would be postpone purchase this one ever since it dvd release for one thing and because i would be somewhat underwhelmed by this director two other horror title ( squirm [ 1976 ] and blue sunshine [ 1977 ] ) and but also the fact that the film itself be say to have be slightly trim for gore on the medium blaster or shriek show 2 disc set . i now chance upon it a a rental and be glad i do because and not only be it superior to the early effort ( at least and on this preliminary assessment ) and but i also find the film to be one of the good imitation of the texas chain saw massacre ( 1974 ) . this factor and however and only help remind me that i have yet to check out another such example wes craven classic the hill have eye ( 1977 ) and whose 2 disc r1 edition from anchor bay i purchase some time ago but and after all and halloween time be fast approach . anyway and the film manage an effortlessly unsettling backwoods atmosphere ( it be shoot in the forest and mountain region of oregon ) with plenty of effective frisson throughout but and thankfully and not too much violence ( even if the last of the villain be dispatch in quite an outrageous fashion . ) . the principal young cast here ( one of them play by jack lemmon son and chris ) isn not quite as obnoxious a those we usually encounter in this type of genre offering despite freely indulge in the shenanigan one associate with teen orient flick and which and by and large and persist to this day . george kennedy appear a a sympathetic ranger while though he doesn not have a lot to do and his characterization be decidedly enhance by make him a lover of plant and animal life . also notable among the local be familiar character actor mike kellin in a nice role a the drunkard who first come into contact with the murderous duo of the narrative his warn to the teenager and naturally and go unheeded but he later able to lead kennedy to them . the hermetic family the teen come across in the wood and then and be eventually reveal to be hide a skeleton in their closet . while one of the girl display genuine curiosity at the intruder presence and the rest be openly hostile to them and and in the case of the burly and uncouth twin and appropriately creepy ( one of them be even prone to maniacal laughter during his rampage ) while at a certain point in the narrative and the ranger even offer an interesting explanation a to the nature of their aggressive and generally uncivilized behavior .
