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.

After playing with our expectations, this turns out to be a very different sort of film.

It really made me laugh, but for some moments I was tearing up because I could relate so much.

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