One of Renée Zellweger's most accomplished performances, elevates this comedy-thriller to unexpected heights. Extremely violent and sexual scenes are here, but Zellweger and Morgan Freeman give it a touch of humanity. The only weak element in this film is Chris Rock's character; he's insensitive, loud, rude and downright unpleasant (going so far as using the C word). But Betty is a model of a friendly, compassionate and beautiful human being.
