"Hey, everyone loved the 2013 one! Let's dial it down 20 notches, have the story be absolutely pointless with no connection or correlation to the other ones and make the most laughable lines for the deadites to say. We'll also kill off all the men instantly so it's female focused, add subtle feminist overtones, and add a transgender for the mOdErN AuDiEnCe. That's what the fans will REALLY want..."
The studio, probably.
I wish I didn't spend money on this. I saw the 2013 one opening day and it was by far the best horror movie theater experience I've ever had. I figured only another Evil Dead could top or come close to that... I was wrong.
