The officers had to shoot Drona. Drona made a bad choice to kill 2 innocent people flying a police helicopter. Drona shouldn't have killed the people, who were flying the helicopter. Drona becomes an approver to send the robbers and their kingpin to jail.
A critic from Rediff.com rated the film two out of five stars and wrote that "Director Karuna Kumar's potboiler seems rather disastrous. Watch it only if you are a fan of Nitin, or if you want to see Priya Mani's bare-dare act".[4]Idlebrain.com's Jeevi in his review gave the film the same rating and stated that "the main drawbacks of the film are incompetent direction and bad villain characterization. When the villain’s character is not etched properly, the heroism does not get elevated. It may find some favor in B and C centers. On a whole, Drona is a badly shot film".[3]
