I must admit I would've preferred more of a Captain Marvel solo movie over this team up event that is The Marvels . I'd still be fine with Ms Marvel and Monica Rambeau being in supporting roles but I kind of feel the character earned a sequel from the previous Captain Marvel box office alone. Unfortunately the audience for the MCU has shifted dramatically since the last movie, as has the quality of the films and streaming shows being made by Marvel Studios. The Marvels pays off the conclusions to two Disney+ shows, Wandavison and Ms Marvel , by bringing together Ms Marvel, aka Kamala Kahn, and Monica Rambeau with Captain Marvel, aka Carol Danvers. While the shows aren't essential viewing for The Marvels it is extremely beneficial having seen each character's backstory over just getting the speed notes version in this movie. In terms of being a sequel it's a direct sequel to Ms Marvel's streaming show, as well as picking up on storylines left open in the origin
