Emily Wood’s review published on Letterboxd :
I love the simple, innocent idea of this film. Why not fly away attached to a thousand balloons? There are some darker undertones in this movie, for me, more than other Pixar movies and I freely admit to weeping like a child at one point. The characters are great and I love the ability Pixar have to create rich, full characters that you love without having them say a word. This is a gorgeous, fun little film which will make you have 'all the feels.'
