It's mediocre. The gist is simple and overly used: a controlling father gets to learn to accept people for who they are but it's practically the only thing they build the franchise on since it's pretty much the growth that already been written around for the first movie. Four movies in and there's no depth to any other characters, that's just lazy.
documentary-like and very poetic; the leading actress amazed me. "what's remembered, leaves" Everybody will eventually go down the road. But why not saying "goodbye", I like this word much more when I recently learned that it originally was an abbreviation of "God be with you". Fantastic use of music!
