All-star cast propels emotional roller coaster
What a strange movie -- interesting -- but strange. 21 Grams spins out of control from the first second and the audience had better hang on for dear life. It's not a film for the lazy filmgoer. The movie pushes non-linear storytelling to the brink of frustration, but remains captivating to the end. Paul Rivers (Sean Penn) is the recipient of Cristina Peck's (Naomi Watts) husband's heart after he is killed in a tragic car accident. Paul seeks Cristina out and they set out to kill Jack Jordan (Benecio Del Toro), the man who accidentally killed Cristina's husband.
