I really feel this movie was quite good. Though I agree with other reviewers also about the poor intro of Male lead ( AK ) , unnecessary dialogues, etc.
AK was very smart and intelligent. He avoided unnecessary speaking. He was very confident and sure about whatever he was saying. He was indeed a good husband. He used to call his pregnant wife whenever he got a little less busy. He didn't decline his wife's call even when he was escaping with Natasha to save her and when Aryan was firing bullets from trench top to kill AK. He didn't let his wife knew that he's in danger when yazhini called him from the hospital to let him hear the heart beat of their unborn child for the first time. He promised his wife that he'll be back for sure when Aryan was shooting at him. He stopped asking questions to Shawn and instantly went back to yazhini when yazhini asked him to come back as she was in pain. He saved his wife when some hooligans came to kill her. His long range sniping was very impressive.
In short he was a very intelligent agent and the best husband. The only thing I didn't like was when he asked yazhini to travel to the last metro station alone but it was the only way to keep yazhini safe.
Yazhini was very smart like her husband. She had all the characteristics of an agent's wife ; smart, confident and fearless. Her strong trust upon her husband took my heart. She was very sure that the hooligans won't be able to even touch her, even when her husband was kilometers away from her. She was sure that her husband's bullet won't hit her and was fearlessly helping her husband to kill the hooligans by taking them near the windows. Inspite of being pregnant, she cooperated and helped her husband in many ways; from guiding AK to reach near Shawn , to telling him where Aryan has kept him by using morse code.
Aryan was comparatively a weak antihero. He was smart but his body language and constant speaking somewhere acted as a wall between him and a powerful villain. He was always talking about how much abled AK was and did a lot of bragging about his capabilities & power.
This movie basically shows the mutual understanding and cooperation of an agent and his ordinary wife in a risky mission. It was a good movie, I enjoyed it but still felt that there should have been some more suspense and masala in the movie.
I would rate this 3.8/5.
