Wasn’t there a rumor that Blumhouse was being precious with their Halloween property?
If so, I see why people are drawing the correlation.
That being said, the third Halloween Blumhouse underperformed massively, so maybe they are loosening up on these legacy IP sequels in an effort to drive interest. As well, their version has not been receiving good word of mouth from initial screenings.
Add to that the fact that we did not get the WB version of The Last of Us this year and allegedly we were supposed to get that version last year. WB holds The Exorcist rights if I recall correctly.
