All in all, I enjoyed the show despite the many holes in its story line, until the middle of the second season. From that point on, the entire story line lacked plausibility. The disappointment began when they began talking about army research being done on soldiers at Ft. Devens, MA despite the fact that "Fort" Devens ceased to exist decades before this show was written. The US Army turned over Ft. Devens to the city of Ayer, MA over a decade earlier than the earliest events mentioned in the plot of this show. It's now known as Devens, MA. By the time most of the events mentioned had supposedly occurred at Ft. Devens, most of the buildings at the old base had been razed or had been bought by civilian companies for use as civilian businesses. So, for hundreds of thousands of former Devens troops watching this show, the poor research done by the writers makes the show a disappointment.
