“Ripper Untold” (*1/2 out of four) was a drably done horror thriller set in 18th century London in which a detective (Jonathan Hansler) and a medical examiner (Chris Bell) start looking into a series of bizarre and gruesome murders; however, they soon begin to suspect that one of them may be the killer who is to become Jack The Ripper. Some sharp dialogue between the two is drowned out by film’s uninspired and dreary presentation and film’s languid pace. At this point, maybe they should leave Bloody Jack alone and let him rust in peace.
