I think this is by far the best picture drama i have watched. It shows Lelouch`s determination to make the world a better place before his Zero plans have started. He was ready to sacrifice himself for humanity if necessary from the beginning. However, that being said, this doesnt confirm he is dead. It just shows he had the resolve to die for his ideals, not to become a last second martyr like some haters are claiming. It may be a bit longer than the rest, having some fillers as well, but its definitely something you should watch. On the side note it also shows Suzaku`s wishto become "dog of the army", knight no.1 in order to gain influence in the Britannian court to hopefully speak for the right of Japanese people, namely to make Japan a better living place for his friends Lelouch and Nunnally.
