I don't understand why people are reviewing this thing based on what they expected it to be when they didn't realize it was a screensaver. It's not a movie or short film; complining that it's boring and has no plot or dialogue seems kind of dense.
This is basically the Pixar equivalent of a video fireplace. It's a cute little ~5 minute loop of Finding Dory/Nemo characters swimming around. It's for running in the background while you relax or while you get on with your life.
Judging it as anything else is pointless.
It's beautiful to look at, very peaceful, and cute. It would be nice if it was a longer loop or if it alternated between a few different sequences, but otherwise, it's a perfect execution of what it is intended to be.
