Gee, and I used to work in television....
When I use "shock," I am leaning toward differentiation and uniqueness. To me, great golf courses have these components.
For example, the fundamental thing wrong with a majority of "me-too" courses is that the golfer cannot/could not tell one hole from the next if shown a photo — or even if plopped down blindfolded in some spot he/she had just a played a few hours earlier. It's all the same, all too often.
Bunker after bunker, look after look and style after style is not enough, usually. This can be overcome with a dramatic (shocking) site, a few natural features or even a few man-made features...but, in general, the lame course (my view) is one that does not have the elements of surprise, differentiation and uniqueness.
By "uniqueness" I am using the word to describe this: That a course should have some elements that not only give each hole (or most holes) their own personality, but that the course as a whole is one we would not / could not find anywhere else. Certainly Pacific Dunes, Cypress Point, and others mentioned here do a great job at that — even when they are described as subtle, there is a shock (awe) that comes from the sum of parts.
In the case of Cypress Point, my position is that the course does have shock value — both in the dramatic site and the surprises that carry the golfer into the woods, beyond the inland dune, out back and over the dune, and — finally — along the sea. And, while doing so, Cypress manages to control itself. It does not whack you up side the head. It does't need to as the site does a decent job of that on its own.
