Everyone is riveting. Amitabh is outstanding. While Abhishek Bachchan seems to have patterned himself well on the Rahul Gandhi-Sachin Pilot Inc in terms of the look and the attitude of the natty, young neta of today, Vidya Balan lends a rare dignity to the image of the Bollywood mom.
With her quiet grace and controlled emotions, she is Mother Courage incarnate. But it's Amitabh's Auro (read aura) that outlives all other performances.
The only actor who seems wasted is Paresh Rawal as the old school dad of Abhishek.
