This viewer couldn't help but think what might have been. Instead of beginning with John's discovery, if we had been given an introduction of the harmony, balance, etc., of the mansion life and it's female world such would have stood in interesting contrast to the story. And a brief moment or two of John in battle, facing death, would have serviced well. Some broader paint strokes might have been used in emphasizing three stages of female life represented by Miss Martha, Edwina and Alicia; e.g., different degrees of wisdom, restraint, charm (or lack of it) and approach all the while there existing a similar desire. Plot wise, I like the amputation as punishment, retribution and/or just-desserts but did not think it had to be a product of Edwina's intrusion into Alicia's lusts. The accident giving rise to the amputation would have been better worked as an intentional act caused by an unidentified resident.
But for the above, this could have been Oscar material. Don't hate me, Sophia.
