Castle Hill basin seem to be a real Marmite climbing area, people either seem to come back raving about it or thinking it was log
In my exerience of peoples views whilst there, which group people landed in seemed to exclusively depend on how desperately bothered they were as to what grade they were climbing.
Almost everyone dropped grades, esecially when conditions weren't perfect, but those who could see past this recognised the fantastic, interesting and varied quality of the climbing, on great features and pure lines with no eliminates [that I found], and very little basic pulling.
I'm not saying anyone who has slated Castle Hill is grade obsessed, this is just what I observed of the people who were there when we were.
