A 2 hour extended coda to Code Geass. A year after the fall of the despised Emperor Lelouch brought about world peace, a nation whose entire livelihood depends on global conflict kidnaps Nunnally and "Zero." This sets off a chain of events which threatens to bring the world back to war.
Meanwhile, CC traipses across the globe, dragging the near-mindless shell of Lelouch in tow. Apparently, the interaction of his "Code" with that of Emperor Charles and Empress Marianne caused Lelouch to become nearly de facto immortal, much like CC - and much like had happened to CC previously, Lelouch's mind has been sealed away in the remnants of the extradimensional plane known as "C's world." The problem is, all the previously known gates into C's World had been destroyed by Lelouch during his reign. The last hope is to find the temple of a splinter faction that split off from the Geass Order cult centuries ago - and bring about the resurrection of the world's most cunning and nefarious villain so that all the sacrifices of Zero's Requiem will not be undone a mere year later.
Ok, it actually sounds a lot cooler than it turned out to be. This premise could have been a great third season. But for a 120 minute movie, all it did was make things super rushed. I can't help but feel a bit let down after watching it. And as I said before, this movie is in the continuity of the other abridged Code Geass summary movies, and that means a lot of things have been retconned. Mao was never a thing, Shirley was not killed by Rolo, and Nina never
sexually abused a piece of academy clubhouse furniture. I was rather disappointed by that second fact, as the death of Shirley was a pivotal point in Lelouch contriving and deciding to execute his "Zero Requiem," and it feels like this retcon robs many characters of development and cheapens the gravitas of events in the series as a whole. However, Shirley doesn't play much of a part in this movie at all, so that helps it from feeling too "disconnected" with accepted canon.
