I'm very interested to read the opinions on this thread as well. I'm definitely with Adam & the two Marks. Birkdale is looked upon as the best course in England by many and it was definitely the most disappointing of the Open rota courses for me, though I've not played Princes. I can't believe that they flattened all that wonderful links land to create the fairways, flat lies every where, greens of course nicely put into amphitheaters tucked into the dunes. Almost reminded me of creating the effect of containment mounding. Sure it looks cool but it's far too unnatural for a links. Fun yes, challenging yes but way down my list of favorite links courses. In England, I'd much rather play, Deal, Royal St. Georges, Rye, Brancaster, Liverpool, Lytham and the list goes on.
It just goes against what I truly love about links golf and makes it more modern parkland golf for me. That being said there are a couple solid par 3's. (personal pat on the back, one of my best rounds ever there and the first time and last time I've ever birdied all par 5's) That was fun but not enough to win me over in terms of architecture.
