I'm gonna say, Tiger Zinda Hai, but again, only one or two movies working won't save Bollywood..!!
See, now after Baahubali, audience wanys big movies with atleast enough entertainment & content to make their money worth, event movies or surprise smaller movies, due to ticket prices being increased day by day, they are very careful in choosing..!!
Neither Tubelight, nor JHMS were looking exciting enough, Raees was looking good so it got excellent opening, now even though there are movies like Judwaa 2, Golmaal 4, Padmavati and even SS, but still i think only TZH will be blockbuster and in case content goes wrong, then who knows, 2017 might become blockbusterless year for Bollywood..!!
