Enjoyable to watch as the characters are rational, real people we can engage with, and the costumes, horses and scenery are great to see. But there are lots of shots of the outside of the house with its many sash windows with three panes of glass horizontally. Inside, the window that the first wife jumps out of is a casement window, symmetrical, which must have the same number of of panes each side. We see lots of shots of that window so how come everyone ignores this? When we see workmen climbing up the outside to put bars on the window, but when we see the job done they are screwed to the inside.
When we learn that Sir Richard has an imbicile brother who is responsible for the supposed ghostly appearances of Sir Richard, we have to guess which appearance of the Sichard was real and which the imbicile brother. When Sir Richard tried to strangle his second wife, was that him or the imbicile brother. If it was him then he is a bit of a rogue anyway, if the brother then he did very well as an actor that even his wife didn't know that it wasn't her husband!
