There's good news and bad news. The good news is that this is an awesome, award-winning good-cop versus evil-villian action flick.
The pacing is rapid, the script is great, the fight scenes are exciting, and the love-story subplot is mature and realistic. In spite of it being primarily a drama, Mohan Raja included the requisite Bollywood-style music interludes for the lovers, complete with seven costume changes in one song. (LOL- We always count the dress changes!) The setting is, of course, the corrupt Indian government. The three primary protagonists of the film do a terrific job in character.
The bad news is that the pacing is so tight that subtitles barely stay on the screen long enough to speed-read. The first 20–30 minutes of the film are all backstory, and it's pretty confusing. It's a Tamil movie, and we saw the Hindi-dubbed version, which was a little annoying. Even if we don't understand either language, we understand that the lips don't match the sound. We nearly turned the film off, and we're so glad we didn't. After the back story, it started to make some sense, and this film turned out to be one terrific action film. It's one of those chess-match style, intelligent conflicts that are always great fun to watch.
