For now, I'll just say 'adhu oru karuthu' and move on. Addressing point by point would take time, and I'm relatively busy at the moment. Let me just say I like both the films. But in a very assured manner, I'd take Zodiac over Citizen X any day of the week and twice on Sundays. In my fleeting tweets, it should be apparent how high I place this film in Fincher's oeuvre. Actually at the very top.
