The film was very good. Bobby Simha acted very well in the movie. Even other actors also acted very well in the movie. Songs and BGM were also good in the movie. But some scenes are so violent.

Karthik (siddharth) is asked by a producer to write and direct a brutal and realistic gangster film complete with violence. Karthik chooses to make a gangster flick about assault sethu (bobby Simha),a ruthless psychopath gangster. Trouble ensues when Karthik's plans to try to get close to sethu through his henchmen backfires miserably. Almost on the verge of getting brutally murdered,Karthik,having gotten within striking distance of sethu,finally reveals that he would like to make a gangster flick about sethu,to which sethu agrees. All goes on according to plan until kayal (lakshmi) sets everything in disorder,putting Karthik's directorial debut and career in jeopardy.

I went to the theatre without much anticipation in this movie even if the trailer looks good. From the first scene itself, I was rooted to this movie. I thought of it as an action movie. But the move cannot be termed in any one genre but it is tailor-made to classify it in all genre. It has romance, comedy, action, suspense and a great story to tell. The director Karthick subburaj stands out in every frame in the movie. There is no forced songs or comedy. Everything comes in flow in this movie. And Unexpected twists till the climax makes you glued till the end. Every actor is done their part well but bobby simha excels all the above. Fine performance by him. Every character has a purpose in the movie. Even the petty shop old man has a small but meaningful character in the movie. I wholeheartedly praise the director and I wish him to make many more great movies in his career.

The first thing that anyone can say after watching the movie is that its a new genre of movie.Its a story of an aspiring director who attempts making a action movie on a don's life, decides to follow such a living rowdy and in the attempt gets caught by the group. Till this point the movie is paced with good action, seriousness and leaves the audience in suspense for the interval.After the interval, the movie has dynamic change in the direction of the story where in the gangster (Assault Sethu) himselves gets interested in the movie on his life and gives all the detail that the director wanted. But what happens after that is completely what you will never expect. The humour has worked out in an extra ordinary way that your hands might pain clapping and ur stomach might pain laughing.The notable performance by Simhaa (Sethu) is added advantage in the movie. The characterization is so powerful that even after seeing him as a comedian in previous movies, you wouldn't feel it anywhere in the first half.I can certainly say the movie has all the gripping elements to make the audience to be involved with the script from few mins from beginning till the end. The movie has achieved what was intended and defines to the meaning of the title (Hot-Cool) (First half-Second Half), But you cannot make a clear choice whether it was a complete movie in spite of the efforts put in the climax to justify it. And the most powerfully introduced character gives all the details of his murders as a recording which also adds to contradictory facts.
