We asked the BuzzFeed Community which canceled TV shows need to come back for at least one more season. Here's what they said:
1. Our Flag Means Death (2022–2023)

2. Julie and the Phantoms (2020)

3. Selfie (2014)

There's literally nothing stronger than my love for a one season series that was canceled 10 years ago.
Number of seasons: 2
"Our Flag Means Death should have been allowed its final season. It was such a groundbreaking show. I've never seen myself portrayed so clearly on screen."
"Our Flag Means Death gave me so much. I have more friends and more respect and love for myself, to name a few. Its inclusive queer storylines, and representation of neurodivergence made me feel seen and respected for the first time in a long time. We deserve to hear our story told and to see what the final season will bring."
Number of seasons: 1
"The cliffhanger was too brutal to not give us more episodes. And the MUSIC we're missing out on without a second season? Unreal omg."
"This was when I REALLY started distancing myself from Netflix, and I've had trust issues ever since. 😭"
Number of seasons: 1
"Selfie was ahead of its time. So many people still want a revival! It had such a great cast, too: Karen Gillan, John Cho, Da'Vine Joy Randolph, David Harewood, and Allyn Rachel. And not to mention that one of the directors of the show fought for John Cho's casting to be the first Asian romantic male in an American rom-com series. There needs to be closure. Netflix and Hulu should get the streaming license for this show!"
"The fact that you can’t rent/buy/stream the first season ANYWHERE anymore is such a shame. Only people who were able to catch it the first time around know how good it is, such a disservice to a great show."
