Let's begin with some minor flaws of the show: there are a few plot holes and inconsistencies in the story, and due to the short running time (6 episodes) the story is somewhat rushed in certain areas.

However, it remains a gripping story which is complemented by great performances from cast and crew. There are some deeper themes underneath the action of the show, including how PTSD negatively affects someone's quality of life (and how it indirectly affects those around them).

The directing/camera work/sound was in my opinion very well done, and the constant state of high alertness that a bodyguard needs to have was palpable as a viewer. At any time, things could escalate quickly. And when it does, it's a matter of life and death.
