The movie prediction question is complicated because it includes feedbacl cycles over styles and tastes and is probably cross-linked to other moves airing at the same time. See e.g. http://www.stat.berkeley.edu/~aldous/157/Old_Projects/kennedy.pdf

The "predict taste buds?" question is better. But even that one contains feedback cycles over tastes. At least on some domains like wine and probably cigarettes and expensive socially consumed goods.
