"Nobody went to see Tideland! I was hoping people would get angry about it but those that saw it didn't want to talk about it. This is the world we're living in, people don't want to discuss things that are actually worth discussing."

It seems to me that we must make a distinction between what is "objective" and what is "measurable" in discussing the question of physical reality, according to quantum mechanics. The state-vector of a system is, indeed, not measurable , in the sense that one cannot ascertain, by experiments performed on the system, precisely (up to proportionality) what the state is; but the state-vector does seem to be (again up to proportionality) a completely objective property of the system, being completely characterized by the results it must give to experiments that one might perform.
