Supernatural: All 15 seasons ranked from worst to best

13. Supernatural season 8

Supernatural season 8 was all about Heaven and Hell. First off, it serves up an electrifying exploration of the celestial beings we’ve come to associate with purity and benevolence, as it dives deep into the ethereal world of angels, using Castiel’s storyline to explore that. As Dean Winchester claws his way back from the relentless grips of Purgatory and attempts to close the gates of Hell with Sam’s help, the plot begins to unfurl, revealing an angelic narrative replete with divine intrigue.

Castiel, our favorite trench-coat-wearing Seraphim, finds himself in an unfamiliar position. With a dramatic twist, he’s resurrected and manipulated by a scheming angel named Naomi, who uses him as a pawn in her celestial game to spy on the Winchesters. This season spins the traditional angelic mythology on its head, resulting in an engrossing saga that fans of Supernatural couldn’t help but relish.

But the surprises don’t stop there. In a riveting twist of time, Sam and Dean return to demon hunting and encounter an unexpected yet familiar face from the past — their own grandfather. As a result of an ambitious time travel spell, he leaps forward from his time to theirs, bringing along secrets that add a whole new dimension to the storyline.

This remarkable encounter uncovers the hidden chronicles of the enigmatic “Men of Letters,” a heritage deeply intertwined with the Winchester legacy (which also plays a part in spinoff The Winchesters). This revelation propels the story forward, adding an enriching layer to the narrative canvas of the show. Thus, season eight masterfully weaves the fascinating strands of angelic lore and family history, creating a Supernatural tapestry that’s hard to look away from.
