If the ambition is to provide two hours of instantly forgettable, popcorn-munching escapism, it succeeds.

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.

Mostly, the movie is committed to the value of a good time.

Strong acting helps the film overcome an uncertain premise and create characters that hold our attention absolutely.
