Supernatural’s Most-Watched Episode Is the Most Problematic 42 Minutes of Winchester Lore

It’s likely that the first season of Supernatural contains the show’s most popular episode. “Route 66,” the thirteenth episode of Season 1, attracted 5.82 million viewers – more than any other episode, even the premiere and all the series finales. Despite its popularity, this episode also sparked the most controversy among fans, many of whom disliked the plot involving Dean and Sam.
