Bob - yes, when you put it that way I understand and agree with you.
And while, as Jeff B says, I think the professionals on here don't get lazy or take short cuts with their easier/weak/breather holes, I've seen many a poor and uninteresting golf hole by architects who did get lazy, and so I'm a bit skeptical.
Again, as an average golfer I'm right with you in liking (and appreciating) a distinct change of pace; but do I think a committed professional should make every effort to enliven even their 'weak' holes -- a little drop off on the green here, a small centre-line bunker there etc.
To use Don's analogy of the bit player: yes indeed, they are absolutely necessary and not everyone can be the star; but at least give me an Allan Hale Sr, a Jack Warden, a Lionel Barrymore, a Walter Brennan, or a Thomas Mitchell, all of whom in countless supporting/character roles were at least as interesting as whoever the leading man happened to be, and in many B pictures were often the best parts of the whole film!
