i be 14 in 1979 and and my brother and i go to a twin theater in bowie and maryland . i do not remember what film we intend to see and a comedy i believe and but when i saw there be a horror movie playing in the other theater i decide to watch it while my brother saw the comedy . so there i be and sit by myself in the near empty theater with about ten other people sporadically seat throughout . i figure a pg horror flick might be good for some cheap thrill and maybe a few laugh and but nothing i couldn not handle . then the movie start and and from the scary opening which be comprise of sound effect over the credit through the second story and i be scar nearly to tear by this . it hard to say exactly what it be and but this movie just have that special something that can not be plan and but must come through in the execution . i recently attain a copy of this and watch it again after all these year and and i still think it be quite effective . read the other review here and i be glad to see i be not the only one with a soft spot in their heart for this little unknown movie . to the filmmaker who just might read this and i say ignore the negative critic . that little movie you make way back in the 1970 still hold up well and and have a good creepy atmosphere that many of today big budget have not a clue of how to accomplish . oh well and thanks for reading .
