A sequel is already in development for release next year, and the rumors associated with the project have suggested that it will spend far more time focusing on Pennywise and his origins.
As many fans of Stephen King adaptations already know, IT only represented one half of Pennywise’s horrific rampage.
With that in mind, it would make quite a bit of sense for his supposedly inconsistent powers to become fleshed out and explained logically.
We will have to wait and see if any of the issues with Pennywise’s powers addressed in this CinemaSins video get rectified or acknowledged in the franchise’s next installment.
