I am going to tell about the poor writing of this movie:
1. How did the glass break so easily containing the diamonds of 50-60 crores?
2. If the plan went correctly, why was Sikandar hesitating while being checked by the security after planning the heist of the high valuable diamonds?
3. How did Jimmy Shergill found only three people to be a suspect only based on instinct knowing there were around 100 others.
4. Why would a robber who was careful in opening the door but forgets to shut the main door and reval the guns and resources that are used during the robbery to Sikandar?
5. How did the bag full of guns went inside the bank?
6. Sikandar could have put the diamonds in his pocket only, why carry a big plant revealing it has something in it.
There are more other points which i can write. but i dont think the write didn't think of those points . I believe it was a lazy writing and try to turn the movie as per the robber's wish.
