Our group's impression was Wentworth is an obscenely expensive, generic parkland course featuring deadly dull architecture without a micron of charm or quirk - with soaking wet, arbitrary rough - all in the shadow of a ridiculous looking faux castle staffed by the rudest group of American-hating assholes this side of Tehran. That was our first stop in England and we nearly went back to Gatwick to catch a flight to Scotland.
To say our collective outlooks were drastically improved walking off #18 at Sunningdale Old the next day improved would be quite an understatement. Aside from Troon, where we were treated like zoo animals, I've been met with unbelievable kindness in the UK and Ireland.
It is quite ironic that my two least favorite golf courses across the pond have the nastiest attitude towards visitors. I had to really think hard about whether I was letting the negative experience color my evaluation of the architectural merit of the courses, but upon reflection, neither course has more than three or four noteworthy holes.
