It's entirely possible that sending the audience out feeling lousy was intentional

It's the kind of movie you'll want to see a second time with someone who hasn't seen it yet, to remember what it was like to watch it for the first time.

Each character in this movie — down to the smallest one — is an individual rather than a type, prone to spontaneous changes of mood and sometimes amusing outbursts of pettiness or ill humor.

Although I seem to have had higher expectations than I thought, the movie is super entertaining.
