Supernatural
Remember the times when Supernatural was good? Without weaving more threads leading the Winchesters towards the angels, Chuck and all this heavenly bunch. With ghosts, urban legends, ancient deities and folklore, and quite a bloody performance. When else did death mean something there? Those were good times, weren’t they?
It’s the Great Pumpkin, Sam Winchester is such an episode. The Winchesters investigate mysterious deaths in a small town and suspect a witch of them. It turns out, however, that this is the ancient demon Samhain, who gave rise to Halloween. The summoned Samhain, once worshiped by the Celts, had the power to summon spirits and zombies. And that’s what he did when he was summoned to Earth, sending them to the students partying in the city. After several bloody incidents (including cooking the girl in a tub with apples), Sam managed to send Samhain back to Hell. At this stage of the series, it was still possible to believe in the Winchester brothers’ ability to exorcise demons and wipe out monsters, with or without demonic blood. Then they both put on the armor and that was where the credibility ended.
This episode is the closest to a typical Halloween formula, as it contains drunken partygoers, and at the same time touches on the theme of the holiday’s origin. Supernatural, however, has quite a few non-Halloween episodes that you can watch on Halloween night. For example: the one with Bloody Mary, the hook killer, the wendigo or the drowned boy, and even the more fun ones like the one where Dean dies a thousand times or when they are trapped in various TV productions.
