True enough. The tones are different though. (So far.) Maybe that's what he means.
That is at least what I
meant with my previous post. Anno is presenting his characters' inner thoughts in Rebuild through different narrative methods than he did in NGE. Even though some or all of the Rebuild narrative methods were present in NGE, and even though some or all of the NGE narrative methods are also used in Rebuild, the emphases are all different, which results in a vastly different experience for the viewer (with regard to "mood" or "atmosphere"), regardless of whether the characters and their inner thoughts are the same between these two works.
But, let's be real, is there a truly "new" concept anymore?
As media theorist Marshall McLuhan would put it, there is nothing "new" that does not simply take the "old" and present it in a novel fashion. It is the medium that determines how the message or content is received and interpreted, regardless of what the content itself actually is about (or whether there even is such content).
So if Anno chooses to present the same message through a new medium*), the end result is "new" in this fashion. However, when you ask for "truly new" in media, you are simply asking for the impossible. Every story or character is always and inevitably
a rehash or variation of a pre-existing story or character archetype.
(Movie and literature studies are devoted to identifying such archetypes and tracking their influence throughout media.)*) My previous post contains a summary of some narrative techniques that Rebuild uses more extensively than NGE to convey the same content. However, you may also consider that four feature length anime movies are a different medium than a 25-minute anime TV series of 26 episodes.
