I've never been satisfied with using mostly stationary vehicles and/or predominantly video screens in major rides. These are ok as diversionary side attractions, but not acceptable IMO as major E ticket headliner rides. It feels like the theme park industry is conceding a lack of ambition and/or budget to create real rides with physical scenery (something Universal's Creatives are lobbying to correct, we'll see about Kong's rumors). It might be hard to do those rides and physical scenery, but it's certainly not impossible. And it's always a lot more satisfying if done right. Similar to many movie makers using CGI even for shots that could and should have been done with practical effects (it's expensive and more difficult, but it still always looks better).
If I can't have a great ride that moves through physical scenery (instead plopping wobbling chairs in front of video screens), i'd rather just stay home and watch the movie (especially with the upcoming wave of virtual reality devices). I've mentioned this in other threads before, but I go to Disney World to be immersed in physical environments. An over-dominance of video screens take me out of that experience.
I also don't agree that a sim is the best way to replicate the flying scenes. I can think of at least two types of existing ride systems that would be better choices. The KUKA vehicles used by Harry Potter moves through physical space and have a ton of range of motion and thrills for flight. Or more recently Europa Park's Arthur and the Invisibles which uses a suspended coaster and dark ride hybrid (a lot of the scenes themselves are lacking, but the ride system is really cool). From what insiders here have said, the third ride (the one originally intended to be the real headliner E ticket pre-budget cuts) was also going to be some sort of flying coaster. A much better choice for replicating a flight ride.
Though i'm sure the bean counters are thrilled that people are ok with the third ride (real ride, real E ticket) being slashed and the lesser sim passed off as the headliner instead. I'm not ok with that, my hopes for this project basically died I found out that the headliner attraction was what people like Martin have described as "Soarin 2.0". I regained a slight amount of hope when the boat ride's concept art was shown, but everything is basically hinging on that ride now...
