The Time Traveler's Wife
The 2022 screen adaptation of The Time Traveler's Wife is probably one of the most controversial cancellations the network has ever gone through with. The novel came out in 2003 and was adapted into a film in 2009 that got mixed reviews, so fans were excited to see the story told on screen again. Sadly, HBO canceled the show shortly after the season finale, and a few months later it was even removed from the company's streaming service. Petitions to revive the series have gone unanswered.
Westworld
Many fans would argue that Westworld got to go on long enough, and some might even say that it went on too long, but they're wrong. The series ran for four seasons on HBO and it managed to stay fresh the entire time – its premise evolving just like the sentient androids it depicted. Westworld was canceled unceremoniously in in 2022 and removed from streaming a few weeks later. Today, its four seasons are available only to rent or purchase.
The Nevers
HBO won a bidding war against other networks and streamers to air The Nevers, only to cancel it after one season. The sci-fi series was set in Victorian-era London and was about a group of women who suddenly began to manifest super powers. It was created by Joss Whedon, whose reputation was dwindling at the time following several allegations of creating a toxic workplace environment on other productions. However, Whedon had left the show before it aired, and it's not entirely clear why the show was canceled.
Lovecraft Country
Lovecraft Country was another book adaptation based on a 2016 novel Matt Ruff. It got glowing reviews during its first season, depicting the life of a young Black man traveling through the segregated United States in the 1950s, while unraveling supernatural mysteries related to the writings of author H.P. Lovecraft. The show was canceled after its first season, in spite of the network teasing a second season weeks earlier. However, a 2021 behind-the-scenes book claimed by James Andrew Miller claimed that there were challenges on the set of the show.
The Brink
The Brink premiered in 2015, and its short run was disappointing to many fans. It starred Jack Black as a low-ranking officer for the U.S. Embassy in Islamabad, and the whole season focused on an evolving geopolitical crisis in Pakistan. The idea was to have each season focus on the same characters dealing with a different public crisis in the world, but it only got one chance.
Game of Thrones
Finally, to put a twist on this premise, many fans would agree that Game of Thrones ended too soon – even with eight seasons. The fantasy drama series petered out in a famously disappointing ending, with character arcs reversing course at the last moment without warning. However, the show was canceled – according to author George R.R. Martin, both he and HBO hoped the show would go on for a few more years, while showrunners David Benioff and D.B. Weiss decided to end it when they did. However, the spinoff House of the Dragon is redeeming Westeros for many fans, and showing them the potential that another season could have had. On social media you can still find some hopeful that a new adaptation might do justice to the story.
