I'll go through the good points first... as always it looks absolutely beautiful, the leaps forward that these movies make in turns of effect and textures are always incredible. And in this case it's the fully human characters, particularly in terms of hair, which are really nicely refined, but also the emotion characters have an amazing look to them.
The concept is also something reasonably fresh and new... we meet the anthropomorphic personifications of Riley's emotions as she moves to a new city and starts a new school (there was the TV show Herman's Head from the 90's which covers some of the same ground)... but this does capture part of that sense of childhood where your emotions seem to come out of nowhere and be beyond your control.
Straying slightly into spoiler territory, the progression from memories that are based on a single emotion at the start of the movie to memories that are made up of multiple emotions at the end also feels pretty right for that transition out of childhood.
There were also some nice moments at the very end of the movie when we were given a chance to see inside other people's heads.
And as very often happens I did have a little teary moment at the emotional resolution of the plot.
But on the flip side, I didn't connect with this movie the way I've connected with previous Pixar movies.
Even with the way the character stories resolved, I didn't really like Amy Poehler's Joy or Phyllis Smith's Sadness who are really the major characters inside Riley's head. And because of the way Riley's character has to change throughout the movie, I found I didn't necessarily like her all that much either at times.
There were also a number of, not quite plot holes, but definitely logical blips or perhaps just cases of "well, what does that mean in the real world" concerning some of the stuff inside Riley's mind.
It's a clever movie, and one that might grow on me with further viewings but I guess I was just expecting to love it more than I did.
