I think that is true most of the time...but there are cases (for me, Giles Run) where it is a legitimate great course but I didn't really enjoy it that much because I don't have a big arm to bomb the huge drives and that course leans toward that...
But I do rate some courses higher than other folks do because they are awesome experiences for me...like Lucky Mud in WA, Horning's Hideout in OR and Rosedale Down Under in KS.
Since I travel so much, I like reviews that help me discern if a course will play to my strengths and likes -- for example on a review for Liberty Park in TN a couple of people listed the steep terrain and the technical straight drives and tons of trees as a con and I thought, "I have to play there".
I try to write reviews that let people judge based on their style and likes--even if they are different than mine...occassionally I'll even be honest about my very biased filters
For me, I try to blend a little subjective (easy) with objective (harder) in my reviews...but mostly they are pretty subjective...
