Beautiful movie. I don't know why people have rated it bad. In my opinion a person who didn't like The Good Dinosaur, he is not even a human being. If someone didn't cry watching the movie it means he doesn't have emotions.
My suggestion to everyone who is gonna watch it for the first time or again is to focus on the background music. It has mesmerizing background music and if you focus on the same while watching it.... I'm sure you will be lost in the story !
It will be my favourite till my last breath. Haven't seen such a touching story in any of the animated movies.
