The last two weekends have been exceptionally bad for Tamil cinema post-GST, which was launched on July 1. Theatres across the state were half empty—a rarity in a state where even low-budget films with a light star-cast attract a full house. “Only during heavy rains or cyclones have we seen the crowds dwindling to this extent. If this trend continues we will have to reduce the number of shows very soon,” says a theatre manager in Vadapalani, the heart of Kollywood. According to the Chennai Box Office indicator, footfalls across multiplexes and single screens came down by 30 per cent for the weekend of July 14 to July 16.
