I really liked this show. Wish it would continue. The storyline and character developments were good in my opinion as they touch up on morality vs duty, justice vs revenge, perspective changes, desires and how that gets in the way, looking for second chances/redemption, changing fate, seeing if they can be forgiven and do right, fighting for what's right even if it's very difficult, etc. The sci-fi element and futuristic time place of this story creates a different society interaction.
