I think the source material and it's history is why this can go for a really long time. Since the 1930s a percentage of the population has been into it. Therefore, almost every living generation now has a segment that has some interest. No other fiction has that going for it.Theres more than 60 years worth of stories for hundreds of characters breh and that's talking about literal word for word adaptations not doing it's own thing like the MCU is
A character like Moon Knight could legit have at least his own trilogy think about that.
They have to reboot it only cuz of actors getting old or not being well received
