It's an amazing museum and this exhibit is not to be missed - but there are definitely some problems. The biggest head-scratcher was that Matthew Barney's Cremaster 3 is being shown in its entirety on two small LCD screens suspended above an installation, in a gallery room full of film stills. Since the film is still impossible to legally see outside of a museum, this leaves the option of standing for an hour and a half, or sitting against a wall. On top of that, since it's showing in a fully lit gallery instead of a screening room, parts of the occasionally very dark film are just hard to see. Especially since so much space was given to other films, this seems crazy. I can only think of two explanations - either there was an assumption that people have already seen Cremaster 3 and only needed a refresher, or Barney didn't agree to a full-scale screening as part of his broader tendency to limit access to the work.
Other highlights included Jan Fabre's amazing self-portrait busts, in which he molds horns of real-life species onto his own head, Lee Bul's somehow acutely Asian robots, and Patricia Piccini's deeply uncanny short about a mermaid. I'm late enough getting to this show I can't justify a full writeup, but suffice it to say, if you live in Tokyo or will be here in the next few weeks, you owe it to yourself to go.
