Not too much is currently known about how he intends to enact those changes over the course of the next few movies, but he did reveal that he plans to make The Crooked Man solo movie stand out by highlighting the titular monster’s roots in British folklore, thus giving it a much stronger fairy tale atmosphere.
Credit where credit is due, the folks working on The Conjuring franchise seem to have figured this out and are subsequently taking steps to improve upon it.

In fact, James Wan recently spoke to EW and admitted that he has plans to flesh out new installments in The Conjuring universe by giving them unique styles and genre sensibilities.
