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

It’s not bad or unwatchable but despite the amplitude of the spectacle, the end result is underwhelming.

This is a small, humorous movie in some ways, but it has a huge heart. What a nice experience.

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.
