The main theme that this series focuses on is the reality of war, which includes the concepts of overcoming fear, accepting loss and the importance of forgiveness through love. There is a fairly decent-sized cast of side characters without being too overwhelming, and there are several romantic interests among them which helps to keep your interest even if you're not super into the main relationship. Though their primary purpose is generally to further the drama, the action scenes are quite well-done and do a good job of making you feel like the characters are truly in danger.
On the negative, the story, at times, is a little confusing and the pacing feels a little off. Given that this is a short series at only 13 episodes, there was perhaps a little too much time spent both on the initial ramping-up to the main conflict and on the denouement after the main conflict.
There are also times you may find yourself questioning the decisions of the characters, or exactly what their motivations are, and, while that is often a good thing to some extent in storytelling, I felt that there could have been a little more gradual hinting given to the watcher so that some things didn't seem quite as sudden when they were revealed. Having said that, most things are tied up by the end, though it may leave some people feeling a little unfulfilled.
In summary, if you're the type of person who focuses a lot on logic, consistency and smooth storytelling, this series may not be for you. On the other hand, if you are more about the character relationships and the drama, while being able to suspend your disbelief regarding some inconsistencies or unexplained phenomenon, you will probably enjoy this show like I did.
