This is a great account of perhaps the most important man hunt in American history which took a decade of patience and plotting and instinctive speculation on part of a focused and obsessive CIA operative. The film covers the Navy SEAL Team 6 operation of May 2011 that killed Usama Bin Laden. Kathryn Bigelow has come out with another thriller after her brilliant `Hurt Locker' which shot Jeremy Renner into fame. This film has another impressive performance by Jessica Chastain as Maya, the CIA operative in Pakistan. This was the best performance by an actress in 2012. She was not even nominated. Meryl Streep was awarded for `The Iron Lady', playing Margaret Thatcher. Maybe, that was an author backed role and the jury tends to tilt towards such performances but Chastain's was the more sensitive one. A great statement by Kathryn Bigelow. She has got style. Chastain was acknowledged by the Broadcast Film Critics Association as the best actress. She is a versatile actress. I was impressed by her performance as Maggie Beauford in `Lawless'. As Maya in this film, she has done a strong portrayal of a stubborn and obstinate CIA operative who targets the couriers that Laden was using while working on a base from Abbottabad, Pakistan.
