If a 'House of Leaves' film were to be made, what would you NEED to see?

As a screenwriter my biggest inspiration has been and will always be this book; a novel so impossible to adapt to the big screen that it's been dubbed an "impossible task". And the hardest task has definitely been mimicking the confusing pages in this film. To fit that theme of inspiration, I've been attempting to do this book justice with a complex and novel accurate film adaptation. I wanted to hear feedback from anyone; what do you think it would NEED to include in either it's cinematography, sound design, plot, or layout? (Assuming nothing was skimmed over- including footnotes)
