I broadly agree with the screen over-saturation point of view, and do really like more 'real' stuff myself. However, I think there are perhaps two points worth making here:
1) There is a distinction to be made between sets and AAs. They are often lumped together as 'real stuff' for the purposes of this argument, but they are actually two quite different things. One achieves an environment, and the other creates character / action. My particular position is that I don't really like animatronics that much (however much you suspend your disbelief, most still fall into categories of 'cool but not really realistic' or 'pretty damn realistic but uncanny valley') but LOVE, love, love physical sets. I think being in the environment is the most important thing about telling a story in the way that rides aim to. Nothing impresses me more than an awesome set. Personally, my perfect design philosophy for rides would be killer physical sets, with musion screens embedded in the sets at various different depths for live-action actors or CGI characters to be projected on to. Why has no one done this yet?
Imagine the town scene of Pirates of the Caribbean, with that awesome great set but the lady with the rolling pin being a live-actor chase projected onto a musion screen placed behind the window. Or imagine SPOILERS (highlight)
the Bellatrix scene in Gringotts (where she drags the train forward), if the entire chamber and the tunnels had been physical sets including the platform Bellatrix stands on, with Bellatrix just being on a musion screen placed on the platform.
2) There is also a distinction to be made between 'all screens' and 'some screens'. Spidey, Transformers and Gringotts are sometimes cited as the evil alliance of completely screen-based attractions, when there are actually loads of physical sets anyway. I agree with the screen argument in the cases of DMMM and Simpsons, but I think it's unfair to target the aformentioned trio as evidence of the ever-increasing slide towards screens when they all contain some
awesome physical sets. The sewer pipe on Spidey and the broken concrete pillars and road debris on Transformers are some of my favourite parts of those rides, and I'm very much assuming the supposedly 40-50' tall set segments of Gringotts will be the same for that ride!
