Piku is a light hearted movie which is breezy and has a good vibe to it. Amitabh Bachchan as Bhaskor Banerjee is a sheer revelation. The look to Big B is really good as he looks like a Bengali who is suffering from chronic constipation. His style and look is casual. His cap and casual shirt look is really remarkable and proves that Big B is indeed a phenomenal actor who doesn’t hesitate in experimenting.
