Well, it's really not all that different with, say, Star Tours. One old article from this fansite called Studio Central expressed such, albeit in a negative light, as they thought that Star Tours doesn't work as well at the Studios as at a castle park:
Setting Star Tours on a soundstage [...] is an enormous cop-out. I thought so the first time I went as a kid – I didn’t know what they were going for, with C-3PO's coffee break area and bulletin board off to the side. Are we going to Endor, or are we watching people make a movie about people going to Endor? Introducing the "working set" idea creates a whole extra layer of stuff to get between the guest and the experience.
