Anyone who has watched the previous 4 parts of CBI series will appreciate this one was better than part 4 nerariyan CBI. But this movie is a bit dragging in first half and no where near CBI parts 1 and 3 or even part 2. If you had watched Mammooty's Truth movie that came in 1997, you can easily predict the villain of this movie. But still definitely one time watchable.
