A Haunting in Venice is Not Another Horror Film

I went into A Haunting in Venice without a clue as to what it was about. I hadn’t even watched the trailer, and I judged the movie on the title alone, so I was expecting some sort of Haunting in Connecticut type film, set in Venice.
I suspected I was wrong a few minutes into the movie when they introduced the quirky main character, Agatha Christie’s legendary Hercule Poirot.
