Director K.V.Anand keeps us engaging for 160 minutes with Kavan. The movie may have been based on some Clichés, but the movie is taken from a fresh perspective of what happens behind the cameras of the media. K.V.Anand is known for thinking out of the box, if you look at his movies "Matraan","Ayan","Anegan",etc.
The movie had a fast screenplay,for instance ,the movie's first 10 minutes was equal to an average Tamil movie, Such fast-paced the movie was. the main plot may have gotten buried upon all the things happening in the movie,the Audience may never even get the time to notice it. "Kavan" prompts the Audience to use their brains to all the things they were oblivious in the past.
Further, reviewing the movie without spoiling was that all the songs were good, HipHop Tamizha has done a good job, the songs will be in your head for a while, although the background scores could have been made more engaging. Coming to the cast,it had "Makkal Selvan" Vijay Sethupathy as the lead and Madonna Sebastin, they both have done a perfect job and the other cast includes actors from 3 Generations like TR and Pandian has helped in making the movie more reachable to all types of audiences. The one scene that was worth mentioning was the Pre-Interval block scene,it was unpredictable and gripping like most of the scenes in the movie. K.V.Anand has used all the cast as perfect as possible, which is where many others fail. Overall the movie will give you the immense satisfaction of watching something never before. So, I suggest you to watch it in theaters.
