Agree with Mark. Train wrecks are induced by bad shots or bad strategy relative to your skill. Golfers hate when architects induce them via design, but recognize it when the architect provides temptations, but they do it to themselves by falling for the sucker punch. They blame themselves and accept it, whereas a really tough, near unputtable green they blame the architect.
Any thinking golfer won't attempt a long shot that doesn't give them a 2 to 1 chance of succeeding. In certain situations, maybe 51%.....The problem with severely contoured greens is they have to putt them and have no choice. That said, I don't mind varying contours, with maybe one green 10% under borderline contours per nine, mostly because of the variety in challenge it provides over putting on the same slope time after time.
A golfer once told me they remember holes that are difficult, pretty, or unusual. Not sure how that ties into this discussion, but think it would apply to contoured greens, if not over done.
