@SilverSun Saitama was an adrenaline junkie... so for him, it made sense... Saiki Kusou also had a good reason with all the negatives and stuff (though he later learns to appreciate them more)...
I feel like these authors just saw that and tried to plug in the trope without actually thinking about the reason. So even though the power is only a benefit, he complains, because other series had the character complain about the power... it's like they want the same result, but don't think about the why.
If the cost of power is what you love, then yes, it would make sense that he'd feel cursed... but instead, for him, the power was basically a free gift without cost... so it's stupid...
@HomeSlice Yes, it's plain stupidity... the author just tried to copy Saitama without the substance.
