These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: Code Geass: Lelouch of Britannia
Complete Monster: Lieutenant Kirkham, who merrily massacres Japanese civilians during the invasion and plans to sell their children as slaves and/or organ donors.
Jumping the Shark: Some reviewers felt the original version of chapter 24 took the slapstick too far and made Lelouch out of character. A rewrite/RetCon tidied things up.
Magnificent Bastard: Lelouch, naturally, is working to become one. Granted, he's not up to the original timeline's standards just yet, but he has his credentials from the North African campaign to expand upon.
Rooting for the Empire: Since Lelouch is on their side, Britannia naturally comes across as the 'protagonist' faction in the war with the EU. The author deliberately tries to remind readers that Britannia is supposed to be the bad guy.
Grey and Gray Morality: He's also reminding us that even if they're generally the bad guys, it shouldn't be as clear cut where people are concerned.
