These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: Kingdom Come
Anvilicious: The series is not exactly subtle in its themes, metaphors and particularly religious symbolism.
Boston Brand's (Deadman) four page cameo. He's even wittier in the novelization.
Magog ended up becoming this for the writers; they initially made him a cliched representation of everything they hated about Nineties Anti-Hero and the culture he represented, but he gained unexpected depth through the writing of the series until he ended up being one of their favourite characters from it.
Nightstar due to being a walking representation of the marriage between fan-favorite coupling Nightwing and Starfire.
"Who bagged Eclipso, huh? Who toasted Ra's Al Ghul? Guys like us, that's who! We saved lives, man!"
And they also note that the traditional heroes never had to deal with threats like Genosyde and the Murder Squad - if they had a better answer for those situations, the anti-heroes are all ears.
When Superman questions Wonder Woman about bringing a lethal weapon (a sword crafted by a deity) to quell a riot, she shoots back that not everyone has built-in deadly powers like heat vision or bullet-proof skin.
Considering that the Joker is an unrepentant mass-murderer that both the system and the 'classic' superheroes haven't dealt with yet, is it any surprise that the Magog's killing him is supported?
