There's nothing to say about Code Geass—except that it's a masterpiece. Lelouch is probably the single best-written character in anime, and I've seen a lot of them. His journey is so well done that the closer you get to the end, the sadder you feel—because you know it will soon be over.
The story: it's as good as it gets it's just intriguing to see where it goes it's filled with ambition.
the art: this anime is really old yet it holds up surprisingly well would even go as far to say it beats others from the same era.
if you like death note I would not waste my time and instantly jump through it I ended up liking it more by the end of It.
PS:As someone who hates mechas usually the way they are used in this anime are more like tools than anything it doesn't feel forced like other mecha animes that I wasn't able to even look at for more than 5s.
