This one of those "based on Agatha Christie" type things. The stories have to be re-written to include lesbians kissings, Miss Marple's sexual experiences, completly invented end-of-pier show starring well-known comics etc etc. It's odd, really, considering that Agatha Christie's books are inordinately popular, that TV companies seem to feel obliged to completely rewrite the stories. Rather like an "Oliver Twist" I saw on TV a year or three ago, which had a completely new plot-line. Surely Dickens and Christie, by their ongoing popularity, deserve a bit better than being converted into opportunities for filming coaches, horse,old cars and trains, and inappropriate sex?
