Ms Henson is not convincing in the part of a detective in NYC or as a former soldier in the Mid-East. Sorry to say it drags the entire show down. The last show was a disaster. She was very unconvincing in her primary role as a cop and a complete failure in portraying a soldier in the field in Afganistan.
Compared to the two male stars she is extremely weak in portraying a tough and intelligent NYC police woman. Blue Bloods and Prime Suspect are examples of women in similar roles, whom are very credible and add, rather than distract, from the episodes.
I really like the program and would like it to continue for many years but I fear her weak performances will shorten the program's life cycle.
