The show had lost some realism already. The characters did everything except commit the crimes and were occasionally ready to be involved in that. Nightmare personal problems and rarely tended to their jobs. The final episode has them out at sea and in an airplane crash far from home. Silly personal interactions follow. The entire Boston medical examiner department at work far from Boston? The remains of everybody's bad script ideas collected for a final episode that leaves the show with a bad taste in your mouth.
