One of the most significant criticisms of "Supernatural" is its lack of LGBTQ+ representation and diversity. Not only are there barely any recurring diverse characters, the ones we do see throughout the show — like Gordon, the vampire Alpha, Raphael, and Uriel — are all villains. We do get some positive Black characters like Agent Henrickson and Missouri Moseley, but not nearly enough for a show spanning 15 years.
Additionally, the LGBTQ+ representation on "Supernatural" is abysmal, especially during the first half of the show. Tasteless gay jokes show up more than actual queer characters, and the characters we do see are often stereotypes, like Dean and Sam cosplayers Demian and Barnes. There's a strong case that Dean struggles with bisexuality throughout the show, but the series makes little more than a joke of this. And that's not to mention the bury your gays trope — from Charlie to Castiel, queer characters don't last in this show.
"The Winchesters" rights these wrongs. Not only does the series showcase three out of six POC leads, but Carlos has a phenomenal LGBTQ+ arc. On top of being non-binary (though he goes by he/him pronouns due to the '70s time period), Carlos flirts with and dates anyone he's attracted to. He has a significant male love interest in the show, which is explored more thoroughly than any of the women he's interested in. Carlos also takes on a heap of demons by swatting them with his holy-water-filled hair, a L'Oréal-esque move that would make even Sam Winchester envious.
