She's got nothing going on with Marvel anymore so I really wouldn't be surprised if she takes this for the easy payday. She's done a few indie films (Asteroid City and North Star), but not been in a big budget film since Black Widow. That fits the mold of someone who simply may want to be on the front of people's minds again.
However, Scarlett Johansson is not the type of actress that typically takes a project that is hot garbage, so if she signs on, I'd have faith that at least on paper, this should be okay and there's plenty of room for her to shine. She's been in plenty of mediocre films that had some potential that they didn't fulfill, however things aren't automatically fixed if they get her, although it could be an encouraging sign.
To me, it's really all about the writing. That's where these films are falling apart.
