I'm writing a book with three main characters (already changed the format a few times, briefly the main character was a police detective, then basically Batman/Mike Haggar, then finally a P.I.).

The problem is I want to introduce the three main characters early on and its just a long prose of worldbuilding for the three of them. The first is the main character (independently wealthy private investigator), the secondary main character, basically a 4chan shitposter with no friends, and an attractive, autistic shut-in woman whose life dramatically changed after a car accident.

I'm thinking about opening the novel with vignettes of them so you can tell what their character traits are like. Is that a bad idea or good one?
