Yes because cosmic energy giving people super powers instead of radiation sickness is so realistic. As is the giant human guy who eats the life forces of planets.
I'm simply saying that the whole "emotional spectrum" stuff is no less silly than the conceits of past eras of comics. It gets played up as this grand, innovative new take on the franchise, but it just seems like adding more silliness.
And different ideas can be equally unrealistic yet not be equally satisfying from a creative or dramatic perspective. Galactus is sheer fantasy, yes, but there's a compelling and thought-provoking story idea behind him, the notion that an entity can be unimaginably dangerous and destructive yet not evil, that even a predator on such a scale has a right to exist because he's just doing what comes naturally. There's an engaging ambiguity there, a philosophical complexity.
Conversely, creating a bunch of duplicate Lantern Corps each powered by a different color-coded emotion may add complication, but not necessarily complexity. If anything, it seems to oversimplify the idea of emotion, reducing each emotion to some pure cosmic absolute -- and making a rather limited selection of emotions to constitute its "spectrum." What's the color of sadness, or amusement, or loneliness, or disappointment, or ironic contempt, or generalized free-floating ennui? Not to mention that it oversimplifies the storytelling if all the organizations, good, bad, and neutral, are ring-bearing lantern corps of one hue or another. That would be like having all of Superman's foes be the last survivors of their respective planets, or having all of Batman's foes be billionaire martial artists with state-of-the-art crime-causing technology. Sure, lots of heroes have villains who are their evil counterparts -- Iron Man has Titanium Man and Iron Monger, Dr. Strange has Baron Mordo, the X-Men have the Brotherhood of Evil Mutants, etc. But they aren't
all just copies of the hero. Iron Man also has the Mandarin, the X-Men have the Sentinels, and the like. Reducing the whole GL mythos to a clash of different types of power ring just seems to be repetitive.
And why do they all use rings and lanterns anyway? I guess it makes sense for the Zamarons if they're an offshoot of the Guardians. And the blue lantern was created by Ganthet in the show, so that makes sense. But why do Atrocitus's forces duplicate the technology of the Guardians? They were attacked by Manhunters, not Green Lanterns, so that couldn't have been the basis for the imitation.
