EVA is regarded as a good series and a definitive mecha series. However, if this is the definitive or a definitive mecha series, I feel sorry for the genre.
Plot: The plot evolves around a boy named shinji, who is called upon to pilot a giant robot called EVA. He meets his father, who ignores him and treats their relationship as purely business and tries to get shinji to stand on his own two feet, which is something shinji continually tries to avoid doing. Gendo, shinji’s father, prefers to spend time with ayanami rei, an emotionless 14 year old girl who spends a lot of time being naked. Fanservice that they attempt to justify through her emotionless character-she simply doesn’t care about being naked.
Of course, it is later revealed that she is some sort of science creation and there are many clone bodies of her (which a couple other characters destroy) so it stands to reason that the big boss of the blace (gendo) would spend more time with rei-given she is basically an artificial creation, they basically need to constantly moniter her. Given how much it costs to make a clone of a simple animal, and they have a giant fluid-filled tank full of rei clones, it would also to be to ensure nothing happens to what amounts to a really expensive body.
Either way, the series constantly pulls off slight sexual innuendo and suggestive themes, some of which are very subtle and very freudian.
