Pretty awful. Seems to be somebody's idea of a 1930s society piece, a cast of eccentric characters who don't matter much, events that trivialize pain and death, unaccountably discordant, chime-like music, all riding on the cachet of Agatha Christie's name. If I had been interested in Agatha Christie before, I'd find better and more interesting things to do after this. Why it wasn't even historically accurate.
