Saw it for the first time last night...
and rather liked it. (Have not read the book.) But I did find it a little flawed. **Spoilers*** For instance, after the first victim was poisoned no one seemed to be too concerend about eating or drinking the food being served to them. And, by the way, what became of the bodies, post mortem? That's never mentioned, excepting the character played by Judith Anderson, whose body was kept in her room, so I am assuming the other corpses were kept in their respective rooms. No one seemed unnerved by this. A house full of dead bodies! Anyway, minor points, I suppose because I still liked it.
