In other cases I felt the installations did not work without the supporting commentary. For example one installation was a woman reading the classical texts about women that Virgina Woolf cites in A Room of One's Own, filmed so that her head obscured the text. Without the blurb explaining it, this just looked like a film of a woman sitting in a library, filmed from the back of her head. I mean, to me the meaning is important, but you couldn't get it from the work without reading the blurb.
I think even more than poetry the presentation of this type of work is inaccessible and even frightening to the casual visitor, entering a big empty space with some earnest chap in glasses watching you watch the exhibit. But I was glad, very glad, to have spent the afternoon looking at these installations. I was definitely affected by them, individually and collectively, even if I didn't understand or enjoy each one.
