I've seen it multiple times and think it's a very good movie. I also enjoy it more than SOTS (though I also do not believe SOTS is offensive in any sense, just kind of boring throughout a lot of it). The quality of these movies have zero bearing on the quality of the rides themselves. A good movie doesn't necessarily make a good ride, and a bad movie doesn't necessarily guarantee a bad ride.
A huge problem is that I do not trust the current crop of imagineers to do a Tiana ride justice. As a new standalone ride that didn't replace anything, it wouldn't have the same astronomical expectations. The problem is that it's not a new ride, it's a replacement of one of the best and most popular rides in the world. At bare minimum, it HAS to be at least as good as Splash Mountain. And that is going to take a miracle to pull off.
The talent and design philosophies that created Splash are gone from the company. It has been over 20 years since Disney opened what I term a "classic style" E ticket (Sinbad at Tokyo), and over 30 years since they did it in the states (Splash itself). Tokyo was/is still getting some cool additions in recent years, but even those are made with modern design philosophies that would be an ill fit for a Splash replacement. And even most of the teams involved with Tokyo projects are no longer with the company as of the past year or two.
Tiana will require a level of detailed and dense physical scenery, animatronic population and storytelling that are pretty much lost from the current crop of imagineers. Charita Carter and her core team do not inspire confidence that they can/will pull it off on their own. That's one reason why I hope what I heard about Tony Baxter (and Bob Weis before he left the company) being substantially creatively involved are true.
