Saw this in-person yesterday.
We were near a friendly family with 2 small children (toddler-ish and pre-teen, from the looks) for this and later on in one of the animal trails.
The kids seemed engaged with the movie when I glanced around the room, but both seemed far more enthusiastic about the animals on the walking trail.
To me, this says that, for those kids, at least, the movie was entertaining in the moment, but seeing the animals was a highlight, and a part of the day they’ll likely take away with them.
That feels like kinda a miss for WDW’s heavily-promoted ‘NEW THING FROM OUR BIG HIT MOVIE’.
