The title of the film is not kaithi because its the story of a prisoner but because when one starts watching it you will be locked up and won't move until the film ends. Initially, I was not interested at all in this film. I didn't even see its trailer. But the super strong positive word of mouth made me curious to watch it. Finally, I have got to see it and everything said about it is true. It keeps you glued on the seat from start to finish. The best thing of the film is its bgm which helps the film to not become dull and makes it worth a theatre experience. Screenplay of the film is watertight despite many things happening around. Performances of everyone is perfect. Karthi once again proves his versatility as dilli. His acting in emotional scenes were amazing. I loved the voice of anbu character (not sure whether its dubbed). Special mention goes to that police constable character who can be called as the second hero of the film. Tamil cinema is famous for family sentiments. Kaithi too has a daughter sentiment and it was very touching. Kudos to karthi and the child. And finally the action sequences. Though unrealistic and bit over the top it was very powerful. Film ends with a cliffhanger making you eager to know about dilli. On the whole, kaithi is a must watch for its interesting plot, tight screenplay and many thrilling moments. Waiting for its sequel. Hats off to lokesh kanakarajan and all the best for thalapathy 64.
