“Winchester” (*1/2 out of four) was a good-looking but drab horror movie about the heiress (Helen Mirren) of the Winchester rifle company who believes she is being haunted by the souls of those killed by her rifle company; a young doctor (Jason Clarke) is subsequently hired to prove she is mentally unfit and moves into her California mansion but soon comes to realize that she might not be a crazy old dame after all. Inventive use of color and design but nothing else about the story is inventive, as it becomes yet another story about a haunted house and hallucinations and characters wondering what’s going on. And speaking of what’s going on- what the hell is Mirren doing in this movie?
