Since Nanoha is such a freaking cult where I rub, I am basically ready to be a fan of it sight unseen and can't wait for the R1 releases. The other day I saw a comic at Avatar's place (BTW, it's very funny, check it out) and it got me thinking.
The comic deals specifically with Nanoha A. I gather that attributes played in the comic are missing from plain Nanoha.
Now, let's look at something else. Everyone knows that Banner of the Stars is "better" than the Crest. Crest is just a middling space opera, whereas Banner is one of the greatest military dramas ever. Those who are not die-hard fans of the franchise and just want to watch the best anime has to offer are advised to skip Crest and see the Banner.
So, is the same true for Nanoha? Should I go to Nanoha A and bypass the original? The sentiment among fans comes pretty close to that. Of course it may be too early to worry about that, but just a thought.
