I was going to make a quip about how reading one wikipiki sharticle doesn't qualify you as an expert, but even
pipi-poopoo has much saucier stuff on Saturn (god) than just "boring agriculture god", including secret mystery cults, child sacrifice (turns out, when a god devours his own infant children in the canonical myths, it's not just weirdness for weirdness' sake, and yes this is yet another allusion to time and death), being the god-king of the Capitoline hill, and of course the previously-mentioned Saturnalia.
And that's just the basic bitch stuff for public consumption. Esotericism and philosophy is where things get really interesting, especially when you realize that much of this stuff never actually died out, got appropriated by gnostic-luciferian-masonic sects, and very much rules the minds of the creators of modern pop-culture.
