Good thriller but without logic.
1)When hunter has gone live in instagram and said we are are planning to climb the tower, why none of her family member and friends tried to came and check whether they are there or anything had happened to them.
2) they had a long rope and if they should have cutted the rope into 4 pieces , 2 of them would have easily came down.
The director should watch how Indian people climb coconut tree with 2 ropes binding to the feet and the object.
3) if they had drone, why they haven’t tied the mobile to it and sent to lower area for finding network?
