The idea of imagined friends has been the texture of some fantasy films. It can be used as a metaphor of self or an element of dealing with trauma or crisis. Writer/Director John Krasinski after making "A Quiet Place" and "A Quiet Place, Part II" wanted to likely make something different but that is an interesting build in jumping from one genre to another. He very much succeeds in certain ways with “IF” while he starts to tow the line on some others.

The approach in any sequel is one of structure and continuation. The interesting idea of "A Quiet Place" and its actual effectiveness was based on the notion of silence. The question becomes how to do that especially with one of your main protagonists is, story-wise, not really available for the second film.
