i just purchase a dvd copy of this film and have subsist on an ancient vhs tape for a few year . ala and the dvd appear to have be master from either very poor stock and or from a vhs tape . the opening sequence be almost unwatchable . even the credit appear blurry . the picture be dark and seem out of focus . i do not remember it be this way when i saw it in the theater . then again and i be six and so what do i know . i still like the psychic or psychotic connection jaeckel have with the shark and although i could definitely lose the hokey shark medallion sequence and which accomplish nothing . i have order a new dvd edition put out by a different company . both version sell very cheaply on ebay . we will see how it go .
