Action is Sundar C's latest film, produced by Ravindran under the banner Trident Arts that has Vishal, Tamannaah, and Aishwarya Lekshmi playing the lead roles, while Ramki, Yogi Babu, Kabir Singh, Shah Ra, Akanksha Puri, and others play crucial supporting roles. The music is composed by Hiphop Tamizha while Dudley handles the cinematography.

The film opens in Istanbul in Turkey, with an ostentatious fight sequence involving Vishal and Tamannaah. Vishal and Tamannaah play the roles of Indian Army officers, Colonel Subhash and Diya respectively. A disaster hits Subhash's family and he sets out to exact revenge for it. In the process, he gets involved in an international network of criminals and decides to hunt down the man behind all this.

Titled Action, the film stays true to the name and the genre in the first half. Barring a small emotional stretch, we are shown one action block after another, and the film gives you lots of mindless entertainment. The way the plot is set up is also clean. But once the second half begins, things go haywire. The screenplay starts lagging a lot and the engagement takes a hit.

Vishal has a meaty role and he carries the role of Subhash quite well, especially the action sequences. The efforts put in by him has translated well on screen. But the same can't be said of Tamannaah, who is underused like the rest of the supporting characters. Aishwarya Lekshmi, Shah Ra and Yogi Babu's characters look more like cameos than supporting roles. Therefore we aren't able to connect well with any of them.

A lot of fight sequences lack realism and except the disaster scene in the initial portions, the other exciting high points don't stand out special. Therefore after a point, the premise becomes overstretched and the story becomes predictable. On the technical front, Hiphop Tamizha and Dudley's work are high on gimmicks but compliments the genre. The cinematic liberties don't help the film's cause either.

Overall, the film had a lot of potential, with an interesting premise. But with no strong conflict after that initial phase, everything built on top of it crumbles like a pack of playing cards. More focussed storytelling and a little attention to detail could have made the film far better.
