The new Marvel series 'Agatha All Along' sees Kathryn Hahn's Agatha Harkness returning after her defeat in 'WandaVision,' where she was left powerless and under Wanda's spell. The series kicks off with Agatha breaking free and teaming up with a mysterious teenager, Joe Locke, to reclaim her lost powers by facing various magical trials alongside an unconventional coven. The show retains the dark humor and television parody elements that characterized its predecessor, while also evolving Agatha's character into a more complex figure, now portrayed as a homicide detective in a moody narrative. The ensemble cast includes notable actors such as Aubrey Plaza and Patti LuPone, enriching the storyline as they navigate the aftermath of Wanda's influence. 'Agatha All Along' aims to provide a fresh take on the character without heavily leaning on comic book lore, focusing instead on character development and entertainment. The series premiered on Disney+ on September 18, 2023, and has been well-received for its clever writing and engaging performances.
