"In my opinion it is the most important film on children to come out of India. I mean in its content," Aamir has written in his blog aamirkhan.com.
"How you all will like it I have no idea, but what I can say is that it has changed the way that I looked at my kids. And, mind you, I think that I am a good father. In fact it changed the way that I look at all children.
"As we take on the burdens of adulthood we often gradually distance ourselves from our children, even our own childhood. This script brought it all back into sharp focus for me," he added.
Taare Zameen Par narrates the story of a dyslexic child and is slated for release on Dec 21.
The versatile actor is extremely excited about the release of his directorial debut.
"Have just reached home after completing the last bit of work on the film. I cannot believe it is finally over. Will be checking the print in a couple days, I hope there wont be any technical delays. The last one month has been killing. Can't wait for it to release now."
However, the actor, who has been fondly termed as a perfectionist, strongly disagrees that the movie is a children's film.
"'Taare...' is a film about children, not a children's film. It is aimed primarily at parents, and potential parents...youngsters who in a few years will become parents."
Aamir is upbeat that his film would succeed in tapping the young audience.
"Of course, since it is about a nine-year-old boy, I expect that kids around eight years and above will identify with the boy and find the film engaging, moving and uplifting.
"I have no idea how kids below eight years will react to the film. Sure there are some fun moments for them like a couple of animation sequences, and the 'Bum bum bole' song, which I believe is a hot favorite with little kids, but in essence the film speaks to an eight years and above audience," penned Aamir.
For the record, Khan's post, which was largely about his films, attracted 358 comments from his fans.
