I've yet to play Lawsonia, but from photos I've seen and reviews I've read the course appears to share a lot of the same attributes as the Langford/Moreau 9 at Marquette Golf Club. The green complexes of those holes, and the land forms they were built on are some of the most beautiful and dramatic I've seen. Yet, when comparing them to the otherworldly Greywalls adjacent to it they come off somewhat old and dated to many retail golfers, who can't appreciate the beauty that lies within and strategy required to play them well. Greywalls is the shiny new toy, whereas the Langford 9 (part of the Heritage course at MGC) is the type of course grandpa played growing up. I hate to say it, but that's the mentality of many younger generation golfers who would rather be oooo'd and ahhh'd then have to strain their brain making sense of the complexities and nuances that make courses like Lawsonia a treat to play. We here get it. Problem is many retail golfers don't. If they play Lawsonia after having golfed Sand Valley, Whistling Straits, Erin Hills, etc. they don't understand what the big deal is about it, because it doesn't overwhelm their senses.
If you're a Golden Age guy like me you seek out courses like Lawsonia, as you understand what makes them truly special and praise-worthy. But I can see how some would find Lawsonia uninspiring if their idea of a great golf course is one that looks unlike anything they've ever seen and is both big in scale and "Wow" factor.
