YMMV / El Eternauta

• Anvilicious: The Second Part is extremely left wing oriented, showing a group of young gaucho-type futuristic cave dwellers fighting a despotic dictatorship of aliens with Juan Salvo as a Che Guevara-like charismatic leader. This doesn't apply for the original first work.
• First Installment Wins: This work has a few controversial editions:
  • El Eternauta, Remake: (1969) By Oesterheld and Breccia. A leftist pamphlet with several drastic changes to the storyline, which coupled with Breccia's weird and experimentalist approach arose an uproar from the fans. Consequently, it got rushed up. It's not merely that the alien invaders are depicted as The Empire, a certain somebody even helps them and all!
  • El Eternauta, Third Part: (1983) By Ongaro, Morhain and Oswal. Just your average sci-fi comic, reusing the characters in some uninspired setting and considered by many to have been made mostly to cash in.
• Moral Event Horizon: Despite fighting an extermination war, the protagonists never torture or execute any enemy. As a matter of fact, being common and decent people, they always are plenty of moral concerns regarding their doings, and never think selfishly, even in the most dire situations.
  • However, in the Darker and Edgier sequel, Salvo makes a Face–Heel Turn, making his disregard to human life somewhat of a shock for the fans of the first part (and even for his comrades in-story).
    • Possible Fridge Logic explanation: those years of deep space wandering really took their toll on Salvo, who used to be a nice and caring family man. The guy is out for revenge.
• They Changed It, Now It Sucks!: While the original series is widely regarded as Made Of Awesome and even taught in schools in Argentina, the Second Part in comparison is considered inferior by many hardcore fans. The same thing is true for the 2000's in-universe sequels made by Solano López and Pablo Maiztegui, though it was a serious product and sold fairly well, itself a miracle given the Argentine economics.
• What Do You Mean, It's for Kids?: The series was aimed for kids and teenagers when it was first released. Kids and teenagers... of the 1950s. Not modern kids. Nowadays, an Alien Invasion seems like a good escapist fiction, but not this one. It starts with a disaster that kills everybody but a few survivors, those survivors violently turn against each other, many characters die in gruesome ways, familiar places of Buenos Aires are destroyed in extricated detail, circumstances are bleak and only get even more bleaker, every Hope Spot is crushed... and no, there is no Happy Ending at the end. Quite the opposite. And if you thought that superhero fiction prepared you for aliens, laser, mind control, super-strength and the like, guess again. And if there is a moment of levity here or there, it's just to make the later disasters even harsher.
