october sky (1999)

I can not say it is a perfect movie however you can watch it comfortably.If you had issues with your father,especially this is more seen between sons and fathers you will like this movie.
It is about following your own ambitions rather than what others want you to follow in your life.If you stand against everything and struggle for your ideals you will be risking to lose your family,friends and others.And it is not suprising that one of the teachers encourage and support ,not someone in the family.
