Really good watch, would watch again, and can recommend.
I'll have to admit, I went into this thinking it would be Disney's yearly racist progressive attempt, so the bar was pretty low.
The movie is actually delightful, and shockingly deep. The title indicates it has to do with the human soul, so I was expecting something along the lines of "Inside" or having to do with jazz, and while it has a rather nice combination of those two things, the attempt on the deep inner workings of the universe in the "inbetween" is incredible.
I imagine everyone will have their own interpretations of what the movie represents mechanically, but the story itself focuses on the pursuit of dreams and happiness combined with the experience of life.
The movie animation is fantastic and the voice actors are all top shelf. The story is awesome, and the characters are strong, deep, and interesting. I find it hard to believe that anyone would actually not like the movie.
The structure is a little basic for something so fantastical, but I think that's by design to keep appeal to most audiences that expect a general family Disney format.
