This is what I think: most productions of Bones lack substance when it comes to romance. Yes, I understand Darker Than Black is not a romantic drama, but if you're going to add romance in there, add it well or leave it out altogether. Don't turn the main character into a lolicon just because you want him to stay "cool" and "nice". I personally don't think there is anything wrong with the characters themselves, neither with their development. In fact, Darker Than Black has many entertaining and well contrasted characters along with in depth development of the main ones we really care about. It's a show that greatly involves the audience to the point of affecting them. It's also not one-sided. Most antagonists get their deserved consolation. Even the minor characters are well developed. They are not just there as plot fillers. Compared to the first season, this season has less action but more of a story to it. I like this contrast between the two seasons. The relaxed pace makes the story more realistic.
This season doesn't explain many unanswered mysteries in season one, however. I kind of like it since it would mean that this series won't end yet, and we still might see even more interestinc characters along with their stories that would unravel the mysteries one by one.
But, if they add more to this harem, I won't even consider watching it.
Darker Than Black would be much more honest as a story if they stop introducing more girls to the series and focus more on unraveling the mysteries from now on (if they don't make season 3, I would rate this show a 5, seriously) I usually prefer action thriller with a touch of romance, but not this time. I don't think it's possible now to introduce any love after basically killing off the girls in the harem one by one and then introducing more to compensate.
