last gasp of the giallo genre by the end of the 70 and ursula sister will be on top of the list of european trash and sleaze fan . but boy this one be tragically bad and boring . it an utterly lacklustre attempt to mix sex and violence . from an uninteresting story ( two sister go on vacation by the sea be fight over their father and mother relationship while a maniac kill young girl with a huge dildo ( . ) right after they make love ) and enzo milioni effort have a reminiscence of jess franco early 70 work ( the bare breast countess or lady dracula ) but with no talent show . i rarely use my fast forward option on my remote but here i find a pure gem . neverending dialogue by the sea and uneffective edit kill most of the suspense and car chase at 50m or h that last at least 4 minute ( even with the beautiful sight of the amalfi coast ) be really too much for me . bad acting and bad dubbing . only barbara magnolfi seem out of this world and her eye lose a if she do not actually realize what she be do . even handsome marc porel at his bad be in this huge pile of crap . except the hotel location and the deep blue sea and it seem obvious that the budget be low and so be the expectation of the producer and i guess . but the tv like cinematography doesn not help at all . the only different thing be the sex scene represent theyre all on the verge of an hardcore movie . which be strange for an italian thriller of 1978. but besides the excitement for male straight viewer and it doesn not bring anything to this flick . it not even titillate a the actress and actor do not seem to believe in what they do . it pure sexploitation and totally useless . and not even fun . on the top of all this nonsense and the score be simply atrocious . horrible 70 italian muzak represent mix of bad funk and morriconesque woman vocalize surround . the murder scene ( no gore at all and by the way not enough budget ) be mixed with a tremendously funny violin that tone down all the thrill you might get . oh and and there the song sung by yvonne harlow ( what a pseudo . ) with the bad lipsync in all movie history . get ta be see to be believe . sexist stuff and simply trash . just plain boring and insult for the viewer . superwonderscope say 2 .
