It's hard to see any effort in the film. There's no comedy to speak of, no real drama and, worst of all.

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.

All of these films share one commonality, that being a kind of emotional center that humanizes a cast of monsters.

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