My problem with the first half of Inside Out was the Sadness character. Why does she keep touching crap? It messes everything up, and she knows it! But she keeps doing it! Ugh. I actually enjoyed Joy, because it was Amy Poehler, and because she seemed to have everything under control, despite being rather possessive. The prime source of conflict made no sense to me. I got over it by the time they got the imaginary friend character, and ended up enjoying the film overall. Looking into the behind the scenes stuff, it looked like Pixar originally wanted to include a whole spectrum of emotions, instead of just 5. I can see how that would have crowded things but it would have made more sense at least. However, at that time, they had given the emotions names that did not really describe what they were, like regular people names. I don't think that would have worked very well.
