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’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+.
