Comicbook.com reports Twitter's trending topics made a lot of TV fans...upset.
"Firefly" was going around the Twittersphere this week, to promote the 2019 Firefly Music Festival.
But for hardcore sci-fi fans, particularly of the cult-classic series 'Firefly', there was a lot of disappointment.
Fans tweeted things like "Please don't name your things firefly. I just had a heart attack before the crippling disappointment."
...and "When you see Firefly trending and you think you?re about to get a reboot you can get behind, but it?s just a music festival."
