Mouse hatred is definitely a thing, and justified or not, I'm hearing that more and more, too.
First, people like to root for the underdog, and while I don't think Disney has ever really been the underdog (at least not anytime recently), as they acquire more and more and more of the movie industry, etc, it becomes really obvious how much power they have, and they start looking a little more "evil empire taking over the world" and a little less "wholesome family fun yay"...and I think the people who feel that way probably extend those feelings toward the parks, too, since they're a really prominent part of the Disney brand.
Second, I know at least some of my friends are turned off by the marketing of WDW vacations being a quintessential part of growing up. It's a marketing campaign based on a guilt trip, and I know a couple of people who say they won't ever go because they don't want to reward that. Do I think that's a driving force in decreasing attendance? No. But it's far from ideal.
I think you've just described my husband. I'm the fan. He's the critic.
He and I have...spirited...discussions about WDW's place in our culture. His view is that it's a "fake" place designed to suck as much money from you in as short a time as possible. He sees it as akin to Vegas. And he hates Vegas.
I argue that rather than being fake, it's imagineered. Rather than trying to look for the authentic, I take joy in discovering the small touches and attention to detail that show the art of the creators.
Sadly, though, the new builds seem more about monetization than imagination. I love MK. It's classic and built for the whole family. Even if you can't or won't ride anything wild, or even anything at all, there's plenty for you to do. I remember the first time I rode the train in MK and saw the details on the backs of rides that were not neglected just because people whipping past on BTMRR wouldn't see. Anyone can ride the carousel or people mover. In HS, the only ride everyone can go on is TSMM. In MK, you can probably spend the better part of a day playing Sorcerers of the Magic Kingdom as a marathon, and it's totally free. In Epcot, you can play Agent P and take in various entertainments around WS. In AK, go around and do the Wilderness Explorers game in addition to looking at the animals.
In HS, there is no equivalent, and if I want to do an 'experience' in GE, it will cost me $100-$200 (not happening). DD is 4, and while she meets the height requirement (barely) for MFSR, I think it might be a bit too intense, especially as I cannot sit next to her. So while there are definitely cool details to look at in GE, there's not really anything for us to DO there, and some of the coolest things to see aren't accessible to us. Even if I set aside my opinion that Oga's Cantina is ridiculously overpriced for drinks, without guaranteed places to sit, I can't reasonably go with DD. I am actually willing to shell out $7 for a glass of blue milk for her, just to take in the ambience of the place, but I won't because my kid is too short to stand at the bar. Maybe my opinion will change when I see SWGE, but from what I've seen and read about it, I think I might have to concede the argument to my husband on this one. It makes me sad.
