The movie is interesting and wonderful acting by all . Everything was going well till they found a very useless way to kill Mr. Oswal . Being from medical background , it was very hard to believe that Just a 5 ml syringe of potassium and that too on his big toe killed him along with very predictable cause of heart attack . If you don’t know , anything injected in the peripheral areas of specially toe , takes time to reach the heart and not sure about drug delivery through tip of big toe . In real life, it may just cause infection of nails and toe and nothing else. You could have done better than this !!
