I think good golf course architecture writing means discussing the good and bad aspects of a golf course with honesty and flair. If you like a golf course, tell me what specific holes or features make it great. If you do not like a course, say so! I think it is worth as much knowing which courses to avoid as knowing which courses to see.
Also, I think any good review of a golf course (especially if it is a positive review) covers two major themes:
1) What makes the course unique.
2) What can a golfer learn from the course.
