The British film industry died in the 1970s and I assume films like this put the knife in, the slow tittles set up what were the most boring first 10 minutes of any film I've seen and it never really livened up
Susan George was totally miscast as the teenager yet was the best thing in it the other 2 had all the charisma of a block of wood, I did fast forward the last 40 minutes to see how it ended and it was even less satisfying than the start
