Riley's father is setting up as an entrepreneur though the move is making her depressed in a way that her parents do not fully appreciate. Her emotions - Joy, Anger, Disgust, Fear and Sadness - are plunged into chaos as they compete for control of her mind.

"Pixar's 15th feature proves to be the greatest idea the toon studio has ever had ... promises to forever change the way people think about the way people think, delivering creative fireworks grounded by a wonderfully relatable family story," said Peter Debruge of Variety.

"A Numbskulls for the digital generation, Inside Out is funny enough, sweet enough and wise enough to sit in an adjacent room to Up and WALL-E," wrote Donald Clarke of the Irish Times.
