Code Geass is about an abandoned prince swearing revenge against his cruel tyrannical father of a king with a grandiose to change the world for the better. A world where his father controls a vast empire that subjugates and oppress lesser powers of the world, a world where the racism and classism is the norm and a corrupted moral ideal dictates that the one holding power is the one that decides what is right. There are also supernatural elements known as geass which the main protagonist uses to his advantage in order to achieve his goals.

Code Geass R1 in general introduces us to the characters and the supernatural elements. In terms of the main plot progression it moved really slowly. But I do believe season 1 is important to really make the viewer understand and recognize the stubborn ideals of many of the important characters. Code Geass R2 almost feel like a reboot of the series trying to tie up loose ends from R1 and is what I believe caused a bumpy plot progression for R2. There are many things happening and several plot points that some don't really seem to matter but is necessary to watch because it is technically not filler (This minor issue does also persist in R1)
However several of the last episodes in R2 really felt like the writers found their footing, sat down and properly plan the story forward towards a well design and satisfying ending.

Code Geass characters and their daily routines really felt jarring sometimes because almost all the main characters are teenagers and they either fight with the government or are secretly rebels. So in an instance they are fighting an all out war and the next they are at school preparing for a carnival. This is really something personally for me I have to stomach in and remind myself: 'it is a 2D Japanese Cartoon... whatever' I am not saying that it detracts from the story too much because these high school drama, slice of life, comedy side of the story can be somewhat endearing or funny at times especially when it is obvious the writers know that these moments are wacky and it shows at how over the top they are presented at times. Still as I said these high school comedy side plots happen simultaneously with serious battles where people fight and die... there can be a real whiplash reaction to the tone of the series at times. But as I said before several of the last episodes towards the end of the story totally throw out all these high school shenanigans and really drive forward the main plot seriously.

The ending is just good it is just really good I cannot possibly explain how good it is without giving spoilers. Basically it really wraps up everything nicely and it is consistent with the motivations of the main protagonists, chef kiss.

Another thing that really stands out is the stubborn ideologies of the main characters and how they are constantly at battle with one another. At times it does not feel like a struggle and contest between characters but of ideals and the characters are representation of those said ideals. These thematic battles of beliefs are consistent throughout R1 and R2 and they come together in a very satisfying way towards the end.

The quality of voice acting, sound design, music, animation are fine. Nothing really amazing and nothing really bad either. It is just... pretty good.

In conclusion what I love about Code Geass is how the story really plays out towards the end. It does suffer from some really drawn out plot lines which is basically slow pacing issues. But boy o boy that ending is one of the most satisfying one I have seen. It is by no means perfect but boy it just feels right.
