This movie defines the greatness of Tamil cinema and is a must for any and all mature movie watchers. The movie has a novel narrative style that is said to be borrowed from the Japanese classic Rashomon. However the style is where it begins and ends. Every character effortlessly blends in the movie. This makes the acting near non-dramatic and appears real. Sivaji in a negative role is the person himself. Pandari Bai as his wife is amazingly apt for the women of that time. It is noteworthy that Sivaji Ganesan raises his voice but never shouts or laughs crazily. Pandari Bai panics but is never shrill. These elements have effectively blended to contribute to the noir theme. "Javert" Seetharaman as detective also amazes us with his unobtrusive role. His role reminds us of the wise sages "searching for the truth". One of the striking elements of the movie is how easily and simply it accepts promiscuity as part of social life. The movie is also a worthy work of direction. Songs are absent but not missed. The narration is taut and perfect. No loose ends here. The narration is so fascinating that the absence of special shots and camera angles do not matter. The B&W contributes to the effectiveness of the forlorn state of the house for most of the movie.
