Since no one else has posted this yet, Inside Out 2 is coming next year.
Looks like they will be looking at puberty, again. Like their last movie didn't already cover that. Also, and it's been a long time since I've seen the first one, but doesn't the premise of this sequel kind of undermine what was stated in the first one? Where there are only the 5 emotions, and they combine to make new ones? Plus, we saw into the heads of other people/animals too and they also only had the 5 basic emotions, so again, where were the others?
