Rating: 8/10 (9 November 2015)

Inside Out is a story where all the emotions of a person are individuals inside a person's brain with a command and control center and the story gets clever and insightful with that theme, especially in dealing with memories of the past.
If you liked Toy Story, Bug's Life, Monster's Inc. and Finding Nemo, you might find that InSide Out is going back to Pixar's roots of stories that have a heart and sole. After a few years of Pixar wondering into superficial movies like Cars, Cars 2, Planes, and Planes 2, Inside Out is refreshing. Amy Poehler, from SNL, re-wrote the entire script for Pixar and voiced a principal role in this cartoon.
The movie is good for people that are already into Pixar films. If you are not into computer animated theatrical films, this movie might not be special enough to grab you. I, myself, am a Pixar animation connoisseur and this addition was one of Pixar's better achievements, in my opinion.
