Titreenp SERIOUSLY. This is what the crap Hollywood still puts out?
ReaderKenka Let's be realistic.
Gurlyndrobb While it doesn't offer any answers, it both thrills and makes you think.
Ogosmith 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.
