Typical slasher movie about a copycat killer, with young people doing things that they shouldn't and getting butchered. I could pretty much predict everything that was going to happen. You'd think that something focusing on Jack the Ripper might be a little more interesting, but "Ripper" doesn't cut it. The most befuddling thing is that Jurgen Prochnow stars in this. He played the submarine captain in "Das Boot" and the terrorist leader in "Air Force One", so what's he doing here? If you want to see a good movie dealing with Jack the Ripper, the choices are: "The Ruling Class" (Peter O'Toole's character ends up believing himself to be Jack the Ripper); "Time After Time" (H.G. Wells chases Jack the Ripper into 1970s San Francisco); and "From Hell" (Johnny Depp plays a detective investigating the murders in 1880s London). And of course some people might include "Dr. Strangelove" (Sterling Hayden plays Gen. Jack Ripper).
All in all, you'll do best to avoid this one.
