I just got back from a WDW trip, during which I was able to ride Tiana’s Bayou Adventure twice. Some aspects of it were better in person, others worse. I’ll start with the positives:
The attraction looks very good from the rest of Frontierland. I was never particularly worried about whether it would blend in, but it does, and it actually adds something quite beautiful to that particular corner of the land, especially when lit up at night.
As for the ride itself, the part before you’re shrunk is much more effective than it comes across on video. The bayou environments are all very lush (I don’t really get the complaints about empty space), and the musical critters are charming and move as they ought to (it’s been brought up repeatedly that they’re not true animatronics, but they’re perfectly well-suited to the job as they are).
Now for the less positive things:
The signage and graphic work are truly dreadful. I didn’t think they could look worse in real life, but they really do, with the exception of the main attraction sign, which is rather pretty, and everything in Critter Co-op, which was clearly worked on by a different (and superior) team.
With a couple of exceptions, the screens really don’t look good, especially in the “shrunken” scene. The worst offender, as others have noted, is the screen showing a giant Tiana and Louis looking in on us—and it doesn’t help that the computer-animated Tiana looks off (on which note, while I don’t think she should have been wearing her princess gown during the bayou scenes, I did come away from the attraction feeling she appears somehow bland and charmless among all those animals).
Most of the animatronics were working, but each of the Mama Odies had its own issues both times I went on the attraction (on two separate days). Even with the animatronics that do work, you experience that weird and awkward pause as they wait for your log to approach.
I have no fundamental issue with the plot of the ride (threadbare though it is), but the way it’s conveyed leaves a lot to be desired. Both times I rode, the timing of the first Mama Odie screen (one of the few that looked good) was off, such that one couldn’t hear the dialogue properly before being shrunk. Had I not already known the story, I would have been mystified as to what what happening.
All in all, it’s about what I expected based on the ride-through videos, even if certain elements were better or worse firsthand. Experiencing it in person certainly hasn’t made me miss Splash Mountain less—quite the opposite.
