Released the same year as Bram Stoker's Dracula, which it reputedly outsold to a significant degree. It's easy to see why it appealed to audiences at the time, given its facination with the Near East, its preoccupation with science, and the inclusion of copious amounts of humor at the expense of the lower class, all major elements of the then-current "trash" literature zeitgeist. Builds nicely to an exciting third act, but the ending's a fizzle.
