Not one to watch anime unless it has some strategic, moral or ethical value. In short some of the stuff I watch is has to have substance to it. Also, it can't be too dark. Example was Deathnote. While it was a psychological thriller, I couldn’t help but having a Friedrich Nietzsche quote stuck it my head. If interested, click on the spoiler. If you ask me, its a good reason to tread carefully.
“He who fights with monsters should look to it that he himself does not become a monster . . . when you gaze long into the abyss the abyss also gazes into you”
-Friedrich Nietzsche
