What do you think is the function of performing arts? Do you see theater? Why? Why not? Do you think it has a purpose or value?

Entertainment is always a big function of the performing arts, but I think a more important function would be criticism of something specific or the world at large. I generally don't go to the theater. Mainly 'cause nothing hops out and grabs my attention. I don't know how to find shows or shows that I like or would interest me.
