If they like laughs, Elio isn't particularly funny. Out of the 4 people who were in the theater, DW and I were the only persons that laughed. I laughed at two scenes. My DW laughed at one scene.
If they like emotional, Elio tries to be emotional and the writing is below average throughout the film and is really strong at the end of the film. The ending kind of saves the movie in my opinion.
The film's story is grounded in trauma. This is an adult topic. A person can certainly have a discussion with children about trauma. Fred Rogers, for instance, was a master of speaking to children about adult topics. It's hard for me to know how kids will react and remain interested in a story about trauma.
The adventure doesn't really work very well. It was boring.
The movie is okay. Its fine. Not a top-tier Pixar movie. Not a bottom of the barrel Pixar film either. I don't think the vast majority of the movie-going audience will regret seeing it in the theater. I won't likely watch it again though when it drops on D+.
