the one turn of events that didn't make sense to me [spoilers]
[SPOILERS AHEAD -- READ NO FURTHER IF YOU HAVE NOT SEEN THE FILM]
Full disclosure: I never read the book. But did Thomas Hardy really write that Mr. Boldwood would take a rifle and shoot Sgt. Troy to death at the end? Throughout the film (and, I assume, throughout the novel), Boldwood was such a mild-mannered, sweet-natured, courteous, civilized gentleman who never even gave a hint that he could hurt a fly, that I was totally stunned when the shot rang out and Troy fell, and it was, of all people, Mr. Boldwood holding the gun. What? His action was quickly described as a "crime of passion" ("You'll be glad to know he won't hang," or words to that effect, said a character later). The scene just made no sense to me. I've heard script writers refer to this sudden turn as a kind of betrayal to the character, one whose personality and life values have been clearly fixed in the minds of the audience members.
Was anyone else struck by the jarring action of Mr. Boldwood? (And educate me -- did Thomas Hardy depict this very scene in his novel?)
