It seems one of the things missing in this discussion is relative time frame. And if i'm wrong Tom D can correct me.
But how many of those courses, where he changed his opinion was it something along the lines of "I saw it in my late teens, early 20s and when i went back 10, 15, 20 years later I thought different"
Because this sort of thing happens to everyone with just about any topic. Work preferences, types of food they like, taste in women, political opinions, religious beliefs, etc, etc.
Play a course 10 times over 2-3 years and your opinion won't likely change much. Play it once or twice and then play it few times more 20 years later....
