I don't like Darkseid when a writer has him fill a role that Mongul was specifically created for: being an intergalactic conqueror for Superman to beat up.
Unfortunately for the character, his popularity in the DCAU led many people to think that Darkseid should be reserved as a nemesis for Superman, and that was apparently just sort of his thing. Darkseid should be a threat
far bigger than Superman, and he should only
very rarely lower himself to using his fists. That's supposed to be a job for Kalibak and the Female Furies and s**t.
Now, I actually liked the big climactic fight between Darkseid and Superman in STAS, mostly because you see that Superman is
clearly outclassed when he's one on one with him. Sure, Clark gets a couple hits in, but Darkseid could obviously kill him at any time, and Superman only wins by using Darkseid's own power against him at the last possible instant before he's killed. Nothing wrong there, IMO. We got to see Darkseid in his glory and Superman managed to save the day without watering down the villain for story convenience.
The problem was Darkseid's resulting popularity after making such a splash in STAS. Now he needed to duke it out with Superman all the damn time, and while he might put Clark down for the count on the rare occasion, he could never really
win since he was the bad guy. So things just got sadder and sadder for him as years passed and his losses piled up.
I remember several specific occasions in the comics where Darkseid even blasted Superman with his omega beams, clearly with the intention of killing him, not just causing pain or whatever. Superman shrugs it off. Knowing what the omega effect is supposed to be, depending on Darkseid's whims, I cry a little inside.
And while I'm on the subject, it always grinds my gears when someone tries to bring up how badass Doomday is because he survived Darkseid's omega beams. I have to wonder on these occasions if those people actually read the story and know what the omega effect is. Darkseid specifically says in the given scene that he's intending to fry Doomsday and keep his remains around in molten rock as a monument. IE: Darkseid did
not try to wipe Doomsday from existence. And by the time Darkseid realized his mistake and was about to correct it, Doomsday knocked him out.
And I didn't read
Final Crisis or any material around it, so I don't have an opinion regarding Darkseid's portrayal in more recent years.
