YMMV / The Eternal

• Audience-Alienating Era: The series takes the concept of the Eternals to a very bleak place, changing almost everything and abandoning the familiar characters. The Questionable Consent and Sex Slave aspects make protagonist Ikaeden very hard to root for, and the series doesn't really try to dwell on them. The Fanservice nudity and squick combines especially badly with those elements. It wasn't a commercial or critical success, and its alternate continuity was never really mentioned again. With the Eternals film boosting the characters popularity, every other Eternals series has been reprinted or digitally republished. The Eternal hasn't.
• Complete Monster: Kurassus is the deranged second-in-command of the Eternal army, and sticks out as vile even when competing with The Celestials. A sexual sadist who happily follows the Celestials' plans in wiping out entire planets of species, Kurassus takes numerous females of whatever species he is currently annihilating to rape and brutally torture to death, invoking revulsion from most of the other Eternals. Expressing nothing but disgust and hatred for every species that isn't himself, Kurassus begins brutally murdering any of the Eternals who try to make their lovers have equal intelligence as themselves, in one notable case killing one Eternal's lover in front of him just to torment him. After nearly being killed by the leader of the Eternals, Ikaeden, Kurassus unleashes dozens of abominable aliens to slaughter any Eternals loyal to Ikaeden, while Kurassus himself severely damages the frontal lobe of Ikaeden's lover, Jeska, reducing her to a superstitious wreck terrified of all Eternals. Even when beaten by Ikaeden, Kurassus continues to taunt him about his lover's condition and dies while cursing him and the rest of his kind for all eternity. Serving as an Expy of Satan himself, Kurassus's sadistic and warmongering personality made him the worst of the Eternals by a considerable margin.
• Squick: Kurassus is a card-carrying villain and extremely unpleasant in various ways, but firmly crosses into squick when sex is involved. He talks about inspecting orifices (saying that Earth's deviants are similar to his memories of Eternal women), we get a glimpse of the doomed deviants in his sex dungeon, and there's a disturbing comment implying certain types of Malevolent Mutilation for his playthings. It's uncomfortable reading.
• Too Bleak, Stopped Caring: Almost nobody in the miniseries elicits any sympathy, violence is rampant, there is tons of sex with dubious consent, and there's a Downer Ending.
