Texhnolyze was neither depressing nor interesting IMO, the only memorable scene was when they spent budget on some guy touching Ran's lips. It did have a well thought plot but wasn't fun overall to watch, and I watched it recently
I liek dark fantasy but I'm not rly big on dark anime. If I wanted to be depressed, I would just think about my future

>Read narcissu!
I read Ame no Maajinaru from the same scenarist, I enjoyed teh detached atmosphere
Is Narikissosu any interesting/fun or just trying to make u cry? Maybe I'd read in the upcoming decades
