You can always count on Agatha Christie for a surprise, and the big twist in A Haunting in Venice is that it's actually a pretty terrific movie.
I say this as a die-hard Christie fan who didn't much care for Kenneth Branagh's earlier adaptations of Murder on the Orient Express and Death on the Nile. Charming as he was in the role of Hercule Poirot, the movies themselves felt like lavish but superfluous retreads of two of the author's best-known classics.
One of the lessons of A Haunting in Venice is that sometimes, it's a good idea to go with weaker source material. Christie's 1969 novel Hallowe'en Party is one of her thinner whodunits, and Branagh and his screenwriter, Michael Green, have smartly overhauled the story, which is now set in 1947 Venice. They've also gleefully embraced the Halloween theme, taking the cozy conventions of the detective story and pushing them in the direction of a full-blown haunted-house thriller.
