And the point is that while she had a major blockbuster success, this will only be her second film since that success; in that time, the losers behind Morbius will have worked on 4 films.
Also, Lim lists herself as a director of the film in her Twitter bio[0], so it seems like a lot more than a maybe at this point.

Separate from all that, I don't understand your larger point about Lim. She went from Crazy Rich Asians which grossed over 200 million, and then went directly to work on Raya, which grossed over 100 million, and now is directing and producing her own movie with hand chosen writing talent. Where exactly is she struggling? And where are writers being forced on her?
