Thematically, Nadia involves the embryonic forms of the ideas and concepts further explored with much more depth in Neon Genesis Evangelion, but those are rather small compared to the more traditional concepts of warfare that it sifts through, primarily focusing on the struggle to maintain one's sense of humanity against the overwhelming odds of war's cruel and cold utilitarianism. The show is marked with the immediately recognisable characteristics of Anno's directorial style, and his importance on the success of the show cannot be understated. Everything, down to the lighting, has his fingerprints all over it, and, most importantly, the writing is filled with his excellent qualitytheatrical speeches and religious reference, and noticeably well written women.

For the most part, Nadia is practically perfect, being consistent in most every aspect, and has a wonderful pacing and tight control of its tone with smooth transition from a lighthearted adventure to a dark and brooding sci-fi. Unfortunately, the infamous Island Arc really is as bad as it's made out to be, taking up about 1/3rd of the total episode count. Before and after it, the show is immaculate, but getting through the Islands Arc, with its noticeable downgrade in everything that makes the series enjoyable, can be a very laborious experience that almost makes you forget why Nadia is so good in the first place. Yet, it is not so bad that it ruins the entire show, as it does eventually end, and a return to form is almost immediate.
