first of all I regret wasting my time watching this movie. I watched it because a friend recommended it saying "It's hilarious". And because i love comedy movies, so I watched it immediately. First of all, I can say that actors were trying to make comedy in the movie but they failed. I actually laughed in one or two scenes but the rest were boring. Away from the comedy part I think this movie was made in a period when Indian movies were still toooooooooo exaggerating. I mean when you watch the fights you will say WTF!!!!!!!!!!! I mean these moves are accepted in something like "The Matrix", "The One", ...... etc But in a comedy/romance movie? C'mon guys it is not acceptable. I can say that the story is good but all these other things made it disappear in a bad context. I don't recommend watching this movie.

Lot of people don't know that its a copied telugu movie which has the name "NEE THO". Vijay as his way, he took another telugu movie even its a flop. The funny thing is he took movie from telugu and again it will dubbed into tollywood. Selection and perfection makes an actor to star. This movie is a scene to scene copy with his supernatural powers. Anyways this was a single line story movie. vijay and genelia gave excellent performance.One has to say hats off to producer Kalaipuli Thanu and debutant director John Mahendran for making a film like "Sachein". Of course, Vijay also has to be congratulated for finally agreeing to move out of the formula movies he has been churning out at regular intervals. This does not mean that "Sachein" is a great or a path-breaking film. A usual romantic film, it is only different from Vijay's other films. However, Vijay himself treads a different path -- especially the comic way he has portrayed Sachein. There is nothing novel in the story; it has been told and re-told umpteen times. A college boy (Sachein) falls in love with the most beautiful girl (Shalini) in the college and even professes his love for her. But the hotheaded girl, who does not believe in puppy love, turns him down. The film ends when she shouts, "Sachein, I love you" at the airport. Don't frown and say, oh no, how many times have we seen this before?Despite all this, the film is interesting. That is mainly because of the way Vijay has played Sachein. He looks like he is having a good time. And looks good too, unlike his recent action films. With a fresh and young Genelia as Shalini, the film is definitely worth a watch. Vijay is there in every frame and he acts, whistles, dances and loves in true style. Even the unnecessary action scenes are done in style. No wonder his fans have given him the epithet 'Ilaya Thalapathi' (younger lieutenant). The difference between the 'Periya Thalapathi' and 'Ilaya Thalapathi' is that this one can actually act. John Mahendran, the writer-director, is the son of the famous Tamil director Mahendran. Mahendran's name is associated with some good films, especially "Uthiripookal". Those familiar with Mahendran's films may frown at "Sachein". If not for anything else, John Mahendran has to be congratulated for giving Vijay such a sweet and endearing role. Also, for choosing a fresh-as-morning dew Genelia for Shalini's role.

Excellent movie from Excellent Actor. He surely one of the most versatile actor that Indian cinema have ever seen. The movie visualization is done well and Vijay had danced well. The the best love romance story in recent years. Vijay's expression is superb when he was in love and comedy scenes with Genelia. Director have done a good job. Comedy had add spice to the movie. Movie standard suits all class of audiences. Eecellent screenplay and climax. The dialogue goes well with the story. Vijay's character have cuteness to attract kids audience to watch it. Vadivelu, Genelia, Bipasha Basu, and other supporting actors have done their job nicely.

Sachin is an unconventional guy who wants to look at life in an unconventional way. He has his own convictions about life which many cannot understand first but at the end of the day, he starts influencing people. So, the film is basically about the character. After watching the film, any youngster might feel that he should also look at life the same way. He is very honest and trustworthy.She also kind a childish and she acted in a simple practical life,the way she smile,very fast get hot and ego,she really have beautiful smile and cute baby face.Here, once again, I have to talk about Sachin's character. He lives life for that particular moment; he is not bothered about yesterday or tomorrow. The entire team of Sachin had the same kind of feeling. I would say the character influenced all of us.iam one of them.This film touch your heart.
