Yes.Absolutely a Pokkisham(treasure) for cinema and story lovers.The entire film was indeed a poetic cine version which was lovable because of richness in Tamil and all the efforts were turned into a success in the visual scenes.
The 1970s were viewed in every frames of the flashback.The director Cheran,camera of Rajesh Yadav have toiled hard to bring a 1970 background...

The storyline was brought back after a long time by Cheran.A movie should be destined to one story and should not deviate in other masalas and Pokkisham has successfully stood devoid of masalas,double meaning,dramatic sentiments.The film is too real and hence this can be called a good and pure cinema.
The story starts when
Lenin(Cheran)'s son
Aryan Rajesh(Mahesh) start reading his father's diary.Then the entire film travel in 1970.The director,cinematographer and music director have given a good input in every frames. The love between
Lenin(Cheran) and Nadheera(PadmaPriya) was pure and the sprouting of love,friendship,respect to woman and the poetic letters were a crown to Cheran.
The love letters were dipped in poetic tamil and exaggeration is the key concept of a poem and it was shown good.The patience which was lacking in lovers of this generation was shown and meanwhile the patience of the old generation lovers were shown clearly and comparitively.
The line,"I am tensed if I dont get a single reply for your message but how they waited for a reply for one month is really unimaginable" by Aryan Rajesh(Mahesh)'s lover . The patience was a necessity and the loneliness created by a lover were explained which is to be appreciated because they are the key concepts needed by the lovers of the present.
The scene which depicts the expectations of Lenin for letters from Nadheera moves like a poem.The comedy was lacking in film but the scene when Lenin goes after the postman to confirm that his letters were taken to the post office because he dont get reply for two letters from Nadheera was really comic. Then the scene when Cheran owe that he talk only to Nadheera and wait for three days by not talking to anybody and the explanation via actions to his neighbours was good but he was forced to talk to the peon of the college to call his lady love were places where we can feel humour.
The love lorn Lenin then yearn for the letters of Nadheera but Nadheera's father cheats everyone and the pain of Lenin was portrayed in his encounter to the Nagai village.Then he will get married but his search for his lady love wont end till the last.But the last three letters he cant post because he dont know the address of Nadheera and Aryan make his voyage to Malaysia and deliver the letters driven and impressed by the love of his father which was a newer concept to tamil cinema.
The last three letters depicts realistic love lorn words by Lenin.The make-up of Nadheera was so good and in the entire film,she has lived as a Muslim. The old lady get-up and the acting was also impressive which tells us the hardwork of PadmaPriya and the director Cheran.
Nadheera(PadmaPriya) was so beautiful and her acting was good showing all the possible reations which was expected.

In this film,the lovers wont even touch each other and so the love is so divine and the expression of love by gift was admirable.The scene when Lenin pleads Nadheera by telling,
""Can I see the face which is like a half moon into a full moon(Moonram pirai mathiri irukkura un mugaththa mulu nilava paaka mudiuma?)"" As I said the film was poetic epic,I have remembered the lines of Vairamuthu in reality in this film.I have given the link below.Go and hear the lines of Vairamuthu and watch the film.The words,""The postman will become a God"" and the poem speaks a lot about love which was literally written by Vairamuthu but visually taken by Cheran.
http://www.youtube.com/watch?v=NZKs56jjkoM The only boring feature was the songs which comes every half an hour.The songs irritate the flow of the film.Even though the film was great devoid of the songs.
The lovers of present talk not more than five to six hours a day and remaining hours through message but I dont know what they will talk.Even they talk for a plenty minutes,they lack in understanding each other and adjusting which was a great loss and its not a true love. If the same lovers were married,they wont spend much time in mobiles as they do while loving.
I can conclude by telling,"""
They love a lot before marriage because only positive characters are exposed during love and after marriage,the full characters can be seen which was harder to learn,adapt,adjust by the lovers and so the love marriages end in failure. The love of present aim at lust and not the hearts."""
