In the 1940s, Columbia Pictures made a series of Boston Blackie films starring Chester Morris. Each of these B-movies lasted about an hour and were consistently enjoyable. In 1951, the series was revived but with a different cast--and a time slot of only 30 minutes. Can the show work with such an abbreviated running time and unfamiliar faces? In the case of "Oil Field Murder", I'd say that the show is a partial success. While the show was very watchable and I liked the dog, the show seemed rushed and only fair--and had too many fist-fights and the plot seemed obvious. Still, Kent Taylor did a decent job and the show is worth seeing.
