A darkened theater with a glowing screen is precisely the sort of liminal space that is the topic of the movie. $20 to fall through the skin of the world for a couple hours? Seems like a no-brainer to me, given how rare and precious any liminal feeling at all is these days. And, if I go support this, maybe they’ll finally make a House of Leaves movie. One can dream.

I'm 150 pages away from the end of my current book. At which point House of Leaves shall become my current book. I'm looking forward to the experience.

I’d hardly consider a movie theater a liminal space. To me a theater is a destination, not a transitional area.

That said I do like your description of “falling through the skin of the world.” A+.
