Great Fiction....But No Solution
I've studied the Ripper slayings for over 30 years, and while this mini-series is well-acted, extremely well-produced, etc., it offers absolutely no credible solution to the identity of the killer. Michael Caine is superb, as well as his sidekick, Ray McAnally. You really understand these detectives and their drive to stop the killings. The subplots involving the romance angle are unnecessary (even though Jane Seymour is gorgeous!) and the psychic angle is just too laughable to be even seriously considered.
Worst of all, the writer(s) have performed the most egregious case of character assassination against the late George Lusk that I have ever seen in a semi-docu-drama film! They turn Lusk from a businessman active in his community and genuinely concerned for the welfare of his neighborhood into a surly sociopathic anarchist, using the murders for his own political ends!
I love this movie as fiction; it's the perfect film to while away a few idle hours on a rainy day. But if you're looking for a solid account of the facts, you'd do better to read Philip Sugden's "Complete History of Jack The Ripper."
