Above average series. Not quite as good as R2, but definitely worth a watch.
Story is fair; it's somewhat interesting but has nothing special about it. At some points It was barely interesting enough to keep me entertained
I Liked the art. It took me a bit to get used to the very lanky character designs, but in the end I liked them. The fight scenes are not good, but that is not this story's strength (and this is one of the older anime I have watched).
I liked the first OP and ending a lot. That is all that stuck out to me for music
I feel like Lelouch's transition from a high school student to a leader of a rebellion is too abrupt. Shirley annoyed me at first but I eventually grew to like her.
Not worth a re-watch in my opinion.
Overall : Fair. However, the second season's ending is worth it, so watch them both.
