The film was excellent. There is only one Song in the film at the end but that also very good. BGM was very good in the movie. Kamal Hassan and Prakash Raj acted very well in the film. Its very thrilling and interesting.

A secret service anti narcotic officer (KAMAL HASSAN) ,is in  search of his kidnapped son and a spy from his own department . KAMAL who is punctured due to the damaging effect of gun shot  has to accomplish the task before he looses his life due to the excessive bleeding.The movie has 1. Lots  of action scenes  2. Kidnapping 3. Dance /disco/ gambling  bars4. Suspense5.very little romance 6. Father son emotions If not for Kamal and Trisha the audience would have got bored as the move fails to keep us on the edge of the seat.

Kamal Hassan is a living legend, it is a know fact that he is one greatest Indian actors to step forward on to the Indian celluloid, and this year we have been lucky to see him in two great films those being Uttama Villain, and Papanasam. Its very rare Kamal Hassan releases more than 1 film year if even one, so 3 releases in a year is extremely rare for him,and with his film he pushes the boundaries of greatness with each film, he is a pathbreaker, so with Thoongaa Vanam the expectations were high. Thoongaa Vanam for the most part meets his standards. Hassan is hercules in the film he shoulders the whole film with the relentless act, the man never gives up. The film which is a french remake is based on the ongoings of just one night, and for the most part Thoongaa Vanam is very gripping,the its a sleek and stylish thriller , and almost on par with Hollywood standards. At the core of the film is the theme,that how far can a father go to save his son, and this a very common theme we have seen in a lot of films, but we get a different take in Thoongaa Vanam. But while the first half the film is great things beginning to slip in the 2nd half, but more on that later.Story wise the film is about the son of a Narcotics Department Cop CK Diwkar getting Kidnapped. The cop now has to return his prized of a big bag of cocaine back to the city kingpin who runs Club. Things start getting messy when his colleagues also start chasing him. All in a Single Night.Acting wise Kamal Hassan is at his best in Thoongaa Vanam, at the age of 60+ the relentlessness he shows on screen is very entertaining, his act is pitch perfect believable, and one believes that he will go to no limits to save his son.The way he performs the action scenes is applaud worthy. Hats off to the evergreen Kamal Hassan. Prakash Raj is good as the comical villain. Sampath Raj is adequate. Trisha is very good, and her action scenes are top notch. Thoongaa Vanam for the most part is highly engaging, the first half of the thriller moves at a fast pace, and the the viewer is completely engaged with the sleek and stylish ongoings. Though the story doesn't have much depth, one doesn't mind this blemish because the film is based on one night so there is no time to establish multiple plot points characters etc.Its supposed to be a racy thriller. The films however tends to becoming very slow in 2nd half and film becomes very muddled in its narrative at many points. At times it feels like we are watching the hero walk in circles playing hide and go seek with the villains. One tends to get bored at some junctures of the film. There are also many unwanted characters introduced in the film, for example what was need of the girl Hassan keeps kissing to hid from the villains. Luckily in the 2nd half there are many amazing realistic action sequences, and some good comic punches by Prakash Raj and co, that make up for the films blemishes.The film is at a running time of 2hrs, and the makers can easily cut 15-20 from the running time to make the film better. The climax at some points(son driving car, and girls at hospital scene)was quite comical but unwanted also.Overall if your a fan of the thriller genre or Kamal Hassan you will surely enjoy Thoongaa Vanam.Kamal Hassan's performance alone is worth the ticket price of the film. So on this extended Diwali weekend the Tamil going audience has the choice between the mass appealing Vedalam or the class appealing Thoongaa Vanam. Both the films for me are about the same,in the there respected genres. But I'll be a little biased this time around and give Thoongaa Vanam, .25* more being a Kamal Hassan fan ;).3.5/5* or 7/10

Thoongaavanam.... What to say about this film.. This is not just a film.. It is a course for young directors how Indian films should be.. No actor dares to act in Indian film without songs.. Ulaga Nayagan already acted thrice in films which doesn't contain songs are Pesum padam, Kuruthipunal, a man like you and now for the fourth time in Thoongaa vanam. Mass actor with class skills will be always one and only kamal hassan. And once again it is proved in this film. A strong crew consisting Prakash Raj, Kishore, Sampath, Trisha Krishnan, Aasha Sharath enough to make audience to go to this film.. But the bgm score which is the vital role of this film made it to the core.. Action sequences doesn't look like Indian way in which a hero will fought with 100 fighters, flying scenes, etc etc. Excellent stunt choreography made this film an action pack thriller.. An authentic story, screenplay, acting from the team. But Kamal Hasaan the man who stole the show with his marana mass acting.. Trisha, Prakash Raj, Kishore did enough what the film wants. The credits song after the film got over was the real suspense to the audience, unexpected. Very well planned screenplay made it like a kuruthipunal, vikram, vetri vizha which even after 20 years will be fresh for the cinema lovers... Everyone must go and watch in the theaters.. Thoongaavanam- a new path for Indian film makers.
