6. There’s Something About Mary (Season 12 – Episode 21)
This particular episode has been disliked by numerous fans who felt it to be out of synch with the vibe of Supernatural. The strong female character of Eileen meets her demise in this episode after fans had developed a liking and adoration for her. Mary Winchester who only returned this season gets brainwashed by British Men of Letters which is just absurd.
5. Carry on (Season 15 – Episode 20)
Carry On is the final episode of the Supernatural series. After having defeated Chuck in the last episode and saving all the universes, the Winchesters are back to their routine job of fighting ordinary monsters and saving lives. While on a Vampire hunt, Dean gets mortally injured and meets his demise. Sam keeps on living his life, having a son, and in the end reuniting with Dean in the heaven. The problem with this episode is certain characters such as Jack, Castiel are absent in the episode. The climax is lackluster, but we have to remember the episode was during the pandemic when there were travel restrictions which prevented many actors from appearing in the episode.
4. Man’s Best Friend with Benefits (Season 8 – Episode 15)
An old pal of the Winchesters named James who had worked on a case with the boys had turned to witchcraft. He suddenly starts having nightmares in which he witnesses the demise of people, but things take an interesting turn when those dreams come true. He enlists the help of Sam and Dean Winchester, but they are having second thoughts after learning that James is into witchcraft now.
3. Bitten (Season 8 – Episode 4)
While Supernatural has experimented with the found footage genre for quite a few times, but the Bitten was one failed experiment. The Winchesters come across the home made videos of people whose lives have been affected by a werewolf. The found footage execution was poor and seemed very unoriginal. The characters seemed unrelatable and less credible. The episode was poorly written and lacked entertaining.
2. Galaxy Brain (Season 15 – Episode 12)
The Winchesters respond to a distress call and rush to the rescue along with Jodie, Jack, and Castiel. Billie who is the new Death pays a visit to the Winchesters. Season 15 isn’t one of the best seasons of the show. This episode is a perfect reminder of how the show has diverted from the Original style which was evident in the initial seasons and became like a dramatic soap opera.
1. Gimme Shelter (Season 15 – Episode 15)
Sam and Dean Winchester go in the pursuit of Amara while Castiel and Jack work together a case that involves the members of a church. This is a filler episode involving the monster of the week. But as it was filmed during the pandemic, plenty of things were missing due to restrictions, making it a poor episode.
