Rumors of the death of the Marvel Cinematic Universe have been greatly exaggerated. While the franchise has had a couple of rough outings of late, the recent success of "Deadpool & Wolverine" and the excitement surrounding the return of Robert Downey Jr. as Doctor Doom shows that a lot of fans are still quite excited by what the future holds. And with the MCU going strong both in theaters and on Disney+, just about anything is possible. But while anything is possible, some things are certainly less likely, and among those items, we can include any sort of an "Avengers" TV series on Disney+. The MCU has teased possibilities with some off-shoot Avengers teams, but Marvel producer Brad Winderbaum told CinemaBlend ahead of the upcoming Marvel TV series "Agatha All Along" that the structure of "Avengers" storytelling would make such a series a challenge at best.
