I went last year as well. I think it's an interesting basic idea, and the geometry and infrastructure layout is quite eyecatching, but I wasn't sure quite what you were meant to _do_ with it as an observer. Even the closest plants aren't that close and the ones at the end could be anything.
One of the aspects of Turbine Hall exhibitions that I like is that they're generally designed so you can walk around and through, interacting with what's going on to at least the extent of choosing your perspective, exploring. Sometimes I enjoy seeing how people are reacting to whatever it is as much as the exhibit itself. There doesn't seem to be much of that here.
