Action-gangster-dramas tend to follow a pattern of origins-rise-conflict-resolution, and Raayan is no different. It, in fact, has a fantastic first half. There is style oozing in every frame, and Dhanush the director takes precedence here, over the writer and performer. Some interesting-yet-familiar conflicts are established, and it gave off the feeling that the Dhanush the writer may at least have a few tricks up his sleeve in the second half (this is such an Indian movie thing - the whole first-half second-half breakdown, i.e.). But then, the writing is really loose; twists happen for the sake of twists - nothing much makes sense. The style quotient still remains on the higher side - the music (Rahman in GOAT mode), the edits (GK Prasanna), and the cinematography (Om Prakash) are top notch. I strongly believe Dhanush benefited from working with his regular collaborators, and that's visible in the film's audio-visual output.
Dushara Vijayan gets a meaty role and she even gets a fantastic set piece in the second half. However, the writing of almost every character (except the protagonist) is two-dimensional, and this includes the primary antagonist played by SJ Suryah. He brings in the eccentric mannerisms (that we didn't get to see in Indian 2), but the writing doesn't elevate him to a major threat. The metaphor of a wolf in the jungle is used to good effect, though I like to believe some Selvaraghavan interventions in the script could've helped. The brothers, played by Kalidas and Sundeep, are also well portrayed, even when their parts are badly written in the second half. Overall, it's still a fine effort from D, the director.
