What's So Special About the Turbine Hall?

The Turbine Hall is unique on many levels. It's size, though perhaps not so impressive compared to spaces in the US, is unparalleled in the UK. The incredibly high ceiling gives you a feeling similar to that which cathedrals and large churches do, that of awe and worship, but without the constraints of silence.
It's a place in which you don't have to switch off your phone, or speak in hushed whispers or only of intelligent observations. You can feel at home enough to scream and shout. Children can play, as can adults, they can touch the art and be a part of the art.
All the pieces are intended to create some sort of physical and emotional effect on the viewers through their interaction. They are not things you have to stand back from or walk around without touching. Perhaps it is this that makes it so successful. One can imagine what would happen if walls were just lined with canvases from one or many artists? It would be completely unimpressive.
Another reason for the popularity and success of the turbine hall is that most of the projects so far have been fun. The turbine hall seems to have become some sort of artistic and mature playground. It's taken art in a completely different direction from the stereotypical sombre, morbid, depressing etc etc art so rife in the scene these days.
