I went to this movie with absolutely no expectations, Arya isn't that big an actor,The director hasn't made any exceptional movies, and so on.
But the movie was really good.It showed a great deal of teamwork and effort, and more importantly it was all well used and portrayed.
Chennai portrayed to the best as in the year 1947. The heroine - Amy Jackson is beautiful and has done a really wonderful job.Her eyes show lots of experience, for a girl of her age.
The story line is similar to that of Lagaan, and many scenes remind you of both lagaan and Rang de basanti, yet the movie has its own originality and inspiration.
Arya isn't portrayed as a hero who fights for freedom,he is portrayed as one who fights for Love.
Editing was awesome, Direction was good. The only negative point of the movie is the songs and BGM. songs don't get in sync with the movie too well. BGM isn't much original and doesn't give the full effect at various scenes.
Still overall the movie is watchable. The reason i rated it 8 was because of the good acting, direction,screenplay,no unwanted comedy or action or songs, and mainly because there was some originality/reality in showing a historic adventure.( something that Ayirathil oruvan lacked ).
The movie may seem a bit lengthy, but don't worry cause it wont bore you out.
Overall - Good movie( don't miss it)
