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

While it doesn't offer any answers, it both thrills and makes you think.

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.

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.
