Yes... Spoilers ahead... But knowing the story wouldn't stop you from going to theaters. Infact you would completely enjoy this film - knitted with scenes that has sassy twists and full of fun. Hero Vijay Sethupathy - wannabe Rowdy right from childhood and this is convinced on title scenes why he is so. There is a scene - he smartly changes the text from Police to Rowdy. OK... Does he become Rowdy? No, He's just self made and runs one stop shop for Rowdyism (graffitied with rates on wall) and comes across heroine Nayanthara (not just heroine; she is fresh, lean, just don't fall for love and physically dumb characteristic; so it requires more than nice looks and she just did great) in an unexpected time, falls flat for her and tries to do "anything" for her. But "anything" she wants is to kill bonafide, brutal and unruly Rowdy who killed her parents. Everybody knows that fake Hero can't do this .. Infact, at a point of time, heroine sets out on her own to kill villain. So how this is accomplished is film that is entertaining, full of wits, musical (not even single duet, but still it's musical) and brilliant new age film making and narrative style. Infact I was expecting emotional closure but still climax went on with comical notes. Credit goes to both Cast and Crew entirely. In short, perfect Rom-Com scoring in all the areas.

Epic acting spree, wonderful performance by all...!!!

Comes a movie, where the hero does anything for his lady love, thrashing things apart, bullying 100s of goons just to witness her cute smile, and that’s how the script is designed for a so-called commercial action flick with above storyline, and here it was, where the ‘Poda Podi’ director Vignesh Sivan made his step, unique, sticking more realistic, settling down with totally different asymmetrical screenplay with symmetrical base line; and how couldn’t it be a successful product, Dhanush playing with Wunderbar.

Actor Vijay Sethupathy suits perfect, post the joyous ‘Kumudha Happy’ face with more of a charm pairing opposite the gorgeous fab Nayanthara who defines justice sporting hearing-impaired women, filling in the laughter moments alongside the counters of ‘cross talk’ RJ Balajee. With the hunger for a hit, facing few troublesome hurdles, Vijay Sethupathy had made his treasure, emoting ideal, what the character asks for.

Actor Partheepan counts as Villain sporting a real don with his usual taunts alongside his rivalry Mansoor Ali Khan.

Credits to director Vignesh Sivan for coming up with script like ‘Naanum Rowdy Thaan’, etching the scope of each character smearing fun, tasting success as a piece of cake.

Anirudh continues hitting his winning streak with Naanum Rowdy Thaan, the tracks topping the charts, making it instant.

Overall, Naanum Rowdy Thaan fills in the laughter to rejoice.
