Ms. Christov-Bakargiev has assembled an immense, unruly organism of a show. It is alternately inspiring — almost visionary — and insufferable, innovative and predictable, meticulous and sentimentally precious. I would not have missed this seething, shape-shifting extravaganza for the world, and I’d rather not see its like again, at least not on this dwarfing, imperious, self-canceling scale.
