And you are right, there IS a slippery slope, especially when utilitarianism is the basis of policy.
>>The acting in “The Island” was terrible, but the premise was not at all invalid and could easily happen in the next decade if allowed.<<
When I first saw “Parts: The Clonus Horror” (starring the late Peter Graves, of “Biography” and “MI” fame) on MST3K, their treatment was, as usually, LOL funny. But the underlying idea — that people would have themselves cloned and those clones would be nothing but walking/talking/living spare parts banks — really struck me as a great plot line: as a cautionary tale when one of the clones decides to be a person and not a parts depot.
I had heard that “The Island” was an attempt to do just that but also it stunk.
There’s still potential gold in them thar plot hills. Want to co-produce a movie? ;)
