Unfortunately, your response to the bizarre story of terror and lust that dare not speak their name is pretty well limited to Roberts' response -- which is, in turn, limited by her technique.
Los Angeles Times:
Sluggish and interminable, Mary Reilly makes good on little of its potential to be disturbing and none of its chance to be emotionally involving.
Mary Reilly is haunting, not only because of its foggy, shadowy settings, but because of the questions it encourages us to ask about ourselves and others.
