We're fans of the work that's done in Tokyo Disneyland/Sea, or Hong Kong Disneyland, or Disney Cruise Line. We're fans of the quality of work that Imagineering used to do when it built EPCOT Center, or Animal Kingdom, or Pleasure Island... Disney has in the past done, and in many places continues to do, stellar work that nobody complains about. Have you seen the new Paint The Night parade yet? It looks brilliant, and I've heard barely a bad word about it. It's just WDW where the decisions of late have been somewhat questionable.
People 'moan and groan' when decisions made by the WDW execs are moan and groan-worthy. I'd say we're just as much fans than the people who just accept any old rubbish because it has the Disney logo on it, or a picture of a princess.
People complain because they care. Like a parent getting angry when their kid goes out drink driving, it's not done just for the sake of it, but for their own wellbeing.
I sometimes think there are two types of Disney fan - those who like Disney because it's Disney, whatever form that may take this year, and those who like themed, immersive and quality entertainment, whoever it is from, but have become lifelong Disney devotees because for so many years, in so many areas, they were the ones doing things right with no competition.
Holding Disney to the standards it used to operate at may be 'moaning and groaning', but the alternative is to accept ever increasing mediocrity, while prices climb ever higher, and that's not just something for the 'moaners' to worry about, but something that will - in the long term - have a negative effect on guests, unquestioning Disney fans, and eventually shareholders pockets.
