This version of the Jack the Ripper saga opens rather poorly by serving up a lot of dull and incredible hoke about a visiting police detective to the London scene by our star player, Lee Patterson, here playing an American detective (although he is in fact a Canadian in real life). Personally, I wouldn't care a fig if our visiting "American" had stayed at home and left the investigation in the more capable hands of Sherlock Holmes. But once the plot really gets into stride, both the story and its presentation improve enormously. Producers/directors/photographers Monty Berman and Robert S. Baker are obviously much more at home with action than standing still. And happily, they have outlaid a fortune (at least by quota quickie standards) on sets and extras.
