I think some of the remarks about Kingsbarns demonstrates a certain level of snobbery. If the course was 75 years old, and people weren't as aware the dunes were created, it would be heralded by many on this site who are now taking shots at it.
Kingsbarns is a delightful wide links with numerous shot options, something that is typically applauded on this site, but apparently is to its detriment in this case.
Perhaps it doesn't all come off 100 per cent of the time, but I find it fascinating that on another part of this site you'll see people holding up Chambers Bay as a fine course, when it, like Kingsbarns, was entirely created. And I doubt that project utilizied someone like Robert Price, who worked with Kingsbarns to try to make the dunes patterns as natural as possible.
The only real criticism I understand is the one about the price, but I think that is just a case of supply/demand economics. If the market wasn't willing to pay it, it wouldn't. The fact is many of my friends who make an annual trip to Scotland, and aren't as wrapped up in the nuances of "natural" vs. "unnatural" dunesscapes, head to the course every year. They love it and I must admit to always having had fun playing there in my five times around the course.
Does that make it great? In my estimation, yes.
