>>37301Nice thread. I'm also displeased by all the creepy sexual stuff plaguing most modern animes.
.hack//SIGN is one of my top favorite older series. It's an early isekai that tells a very serious, dark story. It doesn't have much action but the interactions between characters, and the mystery they are following, are very interesting. Also it has one of the best anime OSTs I've ever heard.
Overall, .hack is a very detailed series involving multiple animes, games, and books. There are other .hack animes but imo SIGN was the best one. I'd watch ROOTS only if you are planning to play GU directly afterward since it's a prequel story for that game. And the other animes only if you are interested in some additional lore.
>>37311I've watched the first 3 series you mentioned and they are also excellent recommendations. Dororo was my favorite out of those.
