I would agree with this - if it's just a projection - that is not a screen ride. I guess what I am more talking about is a combination screen/simulator. A ride that has motion to it, but instead of having physical sets it instead uses some sort of movie screen to tell the story. A good example of this is the Gringotts ride at Universal. It's truly is a motion "coaster" (not truly a coaster because it never "coasts"), but there are absolutely no physical characters of any sort - the entire story is told through the use of projection screens - even though the ride vehicle moves quite significantly. Disney doesn't really have a lot of rides that incorporate screens yet. Soarin and FOP are both screen rides, but essentially a single giant screen. Star Tours is a screen ride as well, but more a motion simulator in that you don't actually go anywhere and it's just a single screen. TSMM is the only one I can think of at Disney that has a vehicle that moves through space, yet the ride itself is entirely screen-based.
Again when taken individually, many of them are wonderful rides. The problem I found at Universal was that so many of them all at once they got old. (I count eleven right now: Three HP rides, Kong, Spider man, Transformers, Simpsons, Fallon, Despicable Me, Shrek, now F&F.) Disney has I think just the four I mentioned above and probably I would include Mission Space in there as a screen ride. (I don't count movies like Philharmagic /ITTBAB/Muppets 3D as screen rides. They aren't rides as they don't try to simulate motion in any way.)
