Had some digital credits with Amazon so decided to rent Flow based on the
97/98 Rotten Tomato scores. We ended up watching it two nights in a row. If you're a cat person, you'll definitely enjoy. If you're not, maybe it'll nudge you that way. No humans, no human dialog, and no need for either.
Note: Three of the four cats that have allowed us to take care of them have been black, so that may account for part of the appeal for us.
