It is one of the tritest observations about India that cricket and Bollywood are our abiding passions. As it turns out, the sentiment is untrue as nothing galvanises us or moves the mob monster to frenzy like politics does. It is the beast that devours our movies and games in one gulp and makes them its own, the progenitor of passionate debates that begin at tea stalls and continue in swish living rooms.
