Yeah, the lack of conflict leaves me a little cold - conflict is the heart of all great stories, after all. RSR is a scene, not a story. That makes it something I like, but not love, in my book. That said, the scene is spectacular, and RSR is immensely fun to ride. Journey to the Center of the Earth, Forbidden Journey and Transformers remain my three favorite rides in the world. But Radiator Springs lurks not too far behind those.
As always, I will need to continue to conduct much, much more research before I can answer this question for certain. ;^) Time to go on more rides!
How's that for a crispy waffle? :-)
