Social consciousness?

Aval Appadithaan (Tamil, She is like that;1978)

Again into movies with themes inappropriate for general Tamil film audience for its social theme and crude (bordering on vulgarity for that era) dialogue. This film was done at end era which in my opinion is considered a watershed. Gone are the days where the characters either gleam with goodness or were bad to the core. The late 70s were the time of social consciousness. Suddenly, making mainstream films in the villages dealing with bread and butter stuff was norm..Actors donned minimal make up and gone were songs and dance-around-the park routine. The birth of new music directors brought music and songs to be played in the background.
Aval Appadithaan is a black and white film with  a slighty different camera work. Manju (Sripriya) is employed in an advertising company run by Thiagu (Rajnikanth). Arun (Kamalhasan), Thiagu's friend from out of town is shooting a documentary on double standards of women position in society. Manju is assigned to help him around.
Manju is a lady disillusioned with life after growing up in a dysfunctional family with a two-timing mother and after two failed relationships. She looks at men with suspicion and scorn. 
Thiagu, an outwardly pious person, is just another blue bearded man who enjoys his drinks and his girls. The protagonist (Arun) is passionate towards his work and takes interest in Manju's life and childhood. Her explosive demeanor and explicit words sometimes frightens him. Perhaps she has bipolar depressive disorder.
Pretty soon Arun falls for Manju but it ambivalent towards her body language. After seeing Manju going out to a function with Thiagu, Arun, who by then had finished his documentary work, decides that Manju is not meant for him. He returns home to marry someone of his father's choice.
Manju who actually had feelings for Arun feels disappointed but moves on.

Some explosive dialogues:
Thiagu: (to Arun on making documentary on plight of women)
"Women should be enjoyed, not analysed".

Manju: (to a socialite who was anxious for not dressing up to be on the camera for an interview)  "You can put your social make-up!"

Manju: (In the closing scenes, asks Arun's new wife) "What do you think of women's liberation?".
Wife: "Oh, I don't know anything about that".
Manju: "No wonder you are happy".

Voice over in the end: She died today. She will be reborn tomorrow. She will die again. She will be reborn again. That's how she is. Aval Appadithaan!
