Darker Than Black's first season was stunning, and one of my favourite seasons from any anime. However, Gemini of the Meteor has had some criticism from fans nostalgic of the initial series. While I won't deny that S2 is very different, focusing more on Suou than on Hei, it nevertheless delivers the kick-ass action and mindblowing plot twists present in season one. I remember, nearing the conclusion of the season, the plot delivered a real sucker punch that caught me completely off-guard, and I quite literally swore aloud; because it was so crazy. All in all, my best advice to any future purchases is to stick with it. It may seem like a waste of time at first, but it picks up very well, and I'll be rewatching soon.
