Dieci piccoli indiani

there have been three (3) remakes of And Then There Were None, my question is WHY? the original version, except for the hockey hollywood type ending, was well nigh perfect. Agatha Christie wrote a fantastic mystery yarn of ten people brought to an isolated island, and eliminated, one by one, until "there were none". the book needed an epilog to explain the solution to was seemed a supernatural tale of punishment. i can understand why Ms Christy's tale had to be somewhat edited for the screen, as there were several overt racist comments and attitudes that had to be expunged. i likewise understand the hollywood need for a happy ending at all times, though i don't agree with that premise. the original And Then There Were None had a superb cast and original story. the only problem is the happy ending, which was a hollywood decree. this film did not need one remake, much less three. i can never understand why the powers that be continually insult the intelligence of their audience, but it seems to be an ongoing problem with them.
