The big picture generates understandable excitement. Sholay will always get more hype than an "art movie", as state-funded cinema used to be called in the days when the state still had the will to hand out dollops to chaps wearing pyjamas and beards. But there is as much to be learnt from the intricacies of the small picture. The most famous portrait ever painted, Mona Lisa, was done on a small canvas.
Politics may be more reasonably compared to artifice rather than art, but the analogy holds.
