The Suicide Squad (not to be confused with Suicide Squad, even though it will be) is not a sequel to the 2016 film, so that should already be giving you hope.
2016’s Suicide Squad wasn’t terrible, but it wasn’t particularly good, either, so it’s nice that the story is getting a second chance, directed by Guardians of the Galaxy’s James Gunn. The cast is even bigger than before, although Gunn has warned us not to get too attached, and includes Margot Robbie (Harley Quinn), Viola Davis (Amanda Waller), Jai Courtney (Captain Boomerang), Joel Kinnaman (Rick Flag), David Dastmalchian (Polka-Dot Man), Daniela Melchior (Ratcatcher), Steve Agee (King Shark), John Cena (potentially Peacemaker), Peter Capaldi, Taika Waititi, Idris Elba (not as a replacement Deadshot), Nathan Fillion, and Flula Borg.
More importantly, Jared Leto doesn’t appear to be involved at all.
The plot will apparently be an amalgamation of several different comics, with primary inspiration coming from the 1987 run written by John Ostrander, even though his Squad didn’t include some of the announced characters, like Harley.
The Suicide Squad has begun production and is set for release on 6 August 2021.
