Yeah, Tiga-Mebius all weren't afraid to explore a lot deeper than the simple lightheartedness, but none of them were "dark" in the term used here. They weren't afraid to look at comparatively mature subject matter, but they didn't make it the focus of the show.

Your point is perfectly accurate, but I'm talking about Urobuchi's style of "dark" writing. It's often not so much about the actual subject matter as "how many people can we kill of to make this series realistic."

You're right though, and I should have mentioned that in my post.
