I liked it, and thought it much better than Finding Dory. I was not smitten with it, however, the way most others were.
I was actually amazed while watching the movie today - there were maybe another 25 people in the theater and they were rolling with laughter, almost without stopping. When we were walking out I heard a few of them saying it was better the second time.
My grandson's liked it a lot, (10 and 6), and better than Finding Dory... and they too found some parts so funny they laughed loud and long... but no where near as much as the rest of the audience.
I thought they were very creative... mimic'ing pet idiosyncrasies. Well worth watching, for me, but no second viewing. - JamesJM
