It used to be Silent Witness was an eminently watchable series. It had tight writing, solid acting and intriguing story lines. No more. The dialog is infantile. The acting unnatural and stagey. But most of all, in this case especially, the guilty party is presented to us in the first half hour. It spoils the rest of the story. There's no mystery who the villain is. But that is just the beginning of plot holes, ridiculous coincidences, stereotypes, sloppy editing and boring conversations. I wonder if the folks behind this series studied the demographics and decided the average Silent Witness viewer has an IQ of 100 or below.
