Fans, please introduce some good anime! I want a god-grade one!

I've already seen the Key trilogy, the Death Note, the sword, the Eva, and the broken I've read all of the banned books in the movie version, including the super-scientific electromagnetic pulse cannon, the four-leaf game, Natsume's friend account, and the two games that fell from the sky. Of course, there are too many others, but there are too many. I've written what I've read, but the majority of the public think it's a classic. Also, I didn't write Death, One Piece, Naruto, not because it's not good, but because I don't like to watch hundreds of episodes that are too long! For personal reasons, please forgive me! If there were any other classic anime, it had to be very, very classic. It would be best if it was an anime from 2003 or above. If it was too old, to be honest, it would look boring. For example, was there any point in playing a classic game from the past on the Little Overlord gaming console? Please introduce some classics and masterpieces! The copying party directly ignored it. It would be a waste to write it. Thank you!
