I think BatB is absolutely a bad use of trackless vehicles (which is why I said it's far from perfect), and the winter scene is terrible. But the Be Our Guest scene and the ballroom as physical spaces look much better than anything in Rat to me -- the physical space I'm inhabiting is usually the most important part of a ride to me, which is why I like Navi River Journey so much more than other people, and why screens do almost nothing for me. The actual physical sensation of moving around in a ride is minor to me. Rat is helped by having some physical props/sets, but you mostly whirl past them to watch the next scene on a screen.
If a ride consists almost entirely of watching something happen on a screen, it's never going to feel very immersive to me. I don't know if that's a result of playing a ton of video games in my life (especially when I was younger) or what, but since I don't care much about the physical sensation, it usually feels like I could get most of the experience just watching it at home. I even feel that way about Flight of Passage to an extent, which is why I don't like it as much as others -- I still enjoy it, though. It's also why Shanghai Pirates has never looked all that great to me.
