Showing only Chennai Box Office to show that Siruthai is the winner is weak. Chennai only represents a portion of Tamil Nadu box office. I could show UK box office as proof to show Kaavalan is the winner. until theres collection data for all of Tamil Nadu and Overseas, its a toss up. Also the reason why Kaavalan is not number 1 in Chennai BoxOffice is because it was release 1 day late and less number of shows. If you look at per show basis, Kaavalan is leading.
