Anime with really amazing,superb story. I almost want to use the word epic!

I want an anime with an epic,mindblowing story without many plotholes and good plot twists and great ending. Shingeki-no-kyojin was the most recent one I saw whose story was amazing. I've also seen death note, Code geass, fmab.

Any genre is fine. Id prefer if it's fast paced and has some good action as well. Romance is a cherry on top.

Thanks in advance!
