renee zellweger absolutely shin a nurse betty and easily one of the most charming and off beat and and lighthearted comedy of the year . when soap opera obsess waitress betty sizemore witness her insensitive husband murder by two hitman ( morgan freeman and chris rock ) and she snap and think the cast member on a reason to love be real . she decide to travel to los angeles to find famed heart specialist dr. david ravell ( a character on the show ) . a the two oddly paired hitman and the caustic rock and the pontificating freeman generate some very fun chemistry and and greg kinnear also have fun with his smarmy offscreen actor persona . renee zellweger turn in an innocent and candy coat and and sometimes terribly sweet performance a nurse betty . she exude goodness and warmth and and be irresistible . while the script sometimes feel like a sit com and be fill with sometimes unbelievable character and contrive situation and zellweger be so likeable and so utterly disarming that it all come together . with just a few splash of black comedy to keep thing interest and a winning performance from zellweger and a great support cast and a competent script and nurse betty be utterly delightful . positive .
