Everyone loves something new Much of the 'theory' arguments are ignored by people once they are in the heat of the moment.. and then it's just a personal experience if it works for them or not. The whole point of all the theory and design is not to exist upon itself, but to deliver on an end objective. You design a way hoping to deliver that objective as successfully with your target audience.
The duration sounds reasonable so far..
The ride/rider interaction is pretty unique for Orlando which is good for it..
The staging seems impressive
To me the question is how much does the motion+video make you forget where you really are.. and how engaging the actual 'trip' you make is. Soarin' is an example of an attraction that works almost solely because of the scale, visuals, and direction (last two being topics significantly hurt in the 2.0 version). Things you can't really replicate fully without doing it live and with everything working together.
I'm a little concerned the 'trip' may be a bit chaotic and so fast you kind of fall into superhero land (think spiderman swinging on webs instead of true speeds)... but I'm not judging yet. I've only watched some of the initial leaked videos and didn't really look at the full duration ones. No rush for me
IMO, it does not feel chaotic. The pacing is excellent, and while there are times that things are happening quickly, they are well-balanced by instances where you find yourself taking time to simply examine the beauty of Pandora. I really look forward to hearing your take on this after you get a chance to experience it. I hope you will post your own review.
