Although a lot longer than most crime documentaries, this doesn't feel like you are watching for 90 minutes, although it may take you a while to get used to the bad choice of narrator. Although the opening is rather cheap, the remaining 85 minutes is thoroughly insightful and unbiased.
After almost 130 years, it is safe to say that Jack The Ripper should now remain unsolved indefinitely as it has becoming too iconic and too much of an industry in itself. This DVD offers enough information to allow the viewer to go away and make their own mind up, just please don't go away thinking you have solved the case and write a book on it.
