No "normal" person goes to DHS and says that "oh that was a thematic mess!" or even really cares about things on such a macro level like that. Sure, it can be argued that they benefit from it without even knowing, but it's simply not a priority or even registers to most guests.
I wouldn't expect any typical guest to be able to articulate that Hollywood Studios is a "thematic mess", but I think we are selling the guests short to suggest they aren't going to at least semi-consciously pick up on the problems. Most of us here can probably tell you what movies we like and which we found disappointing, and most everyone can certainly recognize quality and productions which reflect a superior effort, even though we couldn't begin to describe the failure as one of bad directing, poor lighting choices (whatever that is), and so on. Surely we can expect the average guest, however, to discern a difference between the layout, theme, and organization of any of the other parks compared to the Studios.
They want fun, interesting, innovative attractions. They could care less how they are arranged, that's all icing.
If "how they are arranged" doesn't matter, then
Mystic Manor or
Dumbo would work just as well at any roadside (parking lot) carnival. Indeed, they may have a flying elephant spinner, but its not the same experience. Setting and theme both matter and contribute to the whole of the experience regardless of the extent we are consciously aware of either.
Those are fan concerns, not guest concerns.
They're concerns of both, or there wouldn't be any fans.
If DHS had a half-dozen new remarkable and impressive attractions, that would satisfy guests and they wouldn't care if they fit in with some esoteric theme.
So, if Disney built a half dozen off-the-shelf and minimally themed (or decorated) steel coasters of all types - complete with exposed track and all - that would satisfy most guests? That would certainly be a far cheaper, faster option than developing proper attractions to impress a discerning audience.
The whole "this belongs in X-park" thing and the "theme issues are most important" is an enthusiast notion, not a practical one that reflects most guests.
That concept originates with Disney itself, with themed lands and parks which attempt to transport guests to varied times and locations. Surely you do not mean to suggest it is all just about
rides? Certainly attractions are appropriately the primary focus, but they hardly exist in isolation.
It's like someone who goes to great lengths to set a magnificent holiday dinner table, spares no expense or effort in having the best dishes and utensils, centerpiece, everything grandly themed - and then serving McDonalds on it.
Which is exactly an achievement Disney has long since mastered. McDonald's isn't gourmet dining by any stretch, but it is decent food, and dressing it up in such an elaborate manner creates something more special. If the "thematic mess" at the Studios truly does not register with typical guests, then neither would the Disney parks have become the success they are. Dumbo is of course the classic example (carnivals have flying elephant rides), but even Small World and Pirates are inherently just slow boat rides; Splash Mountain is just a flume ride, Space Mountain in just a bare coaster built indoors with some props. But the whole is more than the sum of its parts.
Disney didn't start things like the WS Character Bus just a few years in to Epcot because there was no demand.
A demand for the Disney characters to be present in Epcot Center doesn't mean the place was boring or unsuccessful without them, it just means that the guests wanted to see characters in a Disney park.
I never found it boring, but all one has to do is look back at the Unofficial Guide's of the time which pointed out that it was best to go to Epcot before MK so kids didn't expect the same kind of entertainment at Epcot and weren't disappointed.
Indeed, Epcot was never meant to be a second version of the Magic Kingdom, and certainly if you went in expecting more of the same, it wouldn't meet your expectations. Anyone who has ever entered the Magic Kingdom expecting to find a whole 'world' of thrill rides and extreme roller coasters - alongside the 'kiddie' rides - has also had their expectations dashed. That doesn't mean either park is lacking (or boring, etc.); It does mean that The Walt Disney Company had created something different and innovative, and a place which would become something a bit special for millions of people.
The problem, however, is that today there is a lack of attention to detail and the standards of theme and a cohesive, planned environment which were previously maintained in Epcot Center. It is, to a surprising extent, growing closer to a second version of the Magic Kingdom - and that's a problem. Typical guests may not be able to articulate the difference in those terms, but that doesn't mean it hasn't already undermined and compromised their vacation experience.
Presentation definitely has some impact, but it's no good if it doesn't serve as a backdrop/enhancement to the meat of the experience - it's like making a cake with 1" of cake and 10" of frosting on top of it.
Interesting analogy, because people do eat chocolate fudge; In fact it is quite delicious! I suppose a thin layer of cake on the bottom of the fudge would also be good, if perhaps a bit 'rich' tasting.
And a very simple, basic attraction can also be set in a highly themed, creative, and immersive context which
richly adds to the experience. That said, I would quickly point out that care must be taken not to put style over substance, with a highly detailed setting but attractions which are lacking (New Fantasyland, arguably).
If that were the case, then AK would have driven attendance at WDW through the roof. It's by far the most intricately themed park in the nation.
If theme and cohesiveness at the macro park level was of the most importance to anyone but theme park enthusiasts on message boards, AK would be the most visited park in the country.
Not when the theme and detail lack something in appeal and widespread interest of the intended audience. The park was seen as too much like a zoo (despite promotion to the contrary), most guests have those closer to home, and it just isn't the sort of thing for which people have traveled to central Florida; The 'animal' theme just isn't sufficiently compelling to most people. Animal Kingdom's main problem, though, has long been just a lack of compelling things to do, much like the Studios, despite its well executed themed environments (style, but lacking in substance, again).
