finally I managed to watch the movie.. quite late but it is ok
When I first heard the announcement of the movie and how they changed the plot, I already put very low hope toward the movie.. so it turned out to be very okay for me
This movie is just a fanservice for Lelouch X C.C. fanbase
and also one of their only chance to show the ultimate Black Knight Squad where they have Kallen, Cordelia, Suzaku, Jeremiah, and Anya as their Knightmare ace, as well as Sayoko, Ohgi for their infiltration squad, and also Lloyd squad for the tech squad. This is also a rare chance where the surviving Britannian family fought under same banner.
The tension when they fought against someone who could reverse time is very high.. Lelouch is actually lose and he managed to win this only because C.C. is unaffected by Geass (I wonder why). Trapping Shamna in unlimited loop is quite cruel but I guess somehow C.C. will enter C world again to set her free (she mentioned that there are still several gates out there)
I felt really weird to see Shirley.. I know that they twisted the new story somehow to revive her, but she really played little part in this movie.. I really don't see anything wrong if we left her died. When Lelouch was offered to fix his past mistakes, I think he will ponder more if he got two regrets (Euphie
and Shirley) instead of only one.
This movie also opened up another plot hole. Just like how Madoka Magica completed their plot in original series and ripped a new plot hole in their movie, I think Code Geass just did the same.
Lelouch, Shamna, and C.C. got Codes.. yet why do we never see C.C. used her Geass? and why does she the only one who is unaffected by Geass?
and the classic question, since Shamna is trapped in eternity, is that mean no one inherit her Code?
I'll just conclude my curiosity by saying that even C.C. does not understand Code.. Inheriting the Code is not simple since we saw at how Lelouch got resurrected without his personality.
Let's just say that C.C. has lived way too long that she really lost her Geass and ability to be affected by Geass
In the end of the movie (after credit), Lelouch has reached the same stage with C.C. and become the new Geass cult leader.. Nice ending
