With all of the recent flops, I feel like it's time to update the list. So far I have (in no particular order):
Concord, Dustborn, Ghostbusters (2016), Matrix (edit) Resurrections, Terminator Dark Fate, Watchmen (HBO), Joker 2, Indiana Jones and the Dial of Destiny, The Acolyte, Willow, Rings of Power, Saint's Row, Forspoken, Starfield, Unknown 9 Awakening, Flintlock, West Side Story, Charlie's Angels, Onward, Turning Red, Luca, Soul, Elemental, Lightyear, and Wish.
Edit: add Suicide Squad: Kill the Justice League, Borderlands (2024), Cowboy Bebop (Netflix), Resident Evil (Netflix), Witcher: Blood Origin, Wheel of Time[?] (Amazon), Agatha All Along, Star Wars Outlaws, Velma, and The Marvels.
Yeah, but it did make over a billion at the box office. It doesn't belong with the rest of these, imho.
fair, maybe put it in the category of harbinger of downfall or something (not added to this list)
