I mostly watch sci-fi from the 80s and 90s although I have seen other types of anime from newer times. I'm currently watching Ginga Eiyuu Densetsu (Legend of the Galactic Heroes) and it's really good. I love military drama, and the main characters are all thought out and believable. It's not easy to make a show with so many characters and have most of them be memorable. I consider the 80s-90s to be the height of anime. But there are still shows being made that are good. I just think the pacing and writing of most of the shows made back are of a higher quality as compared to the 00s-10s. The look of cel animation and the style of sci-fi aesthetics back then also personally appeals to me. Not to say there weren't shitty, low-quality anime being produced back then, I just think the good shows made are generally superior to the good shows being made now.
