I'll start:
My favorite movie is 'Rain man'.
The main character of the movie is managing a small company.
His relationship with his father was bad. They had never met for over ten years.
When his father died, he was notified that he could not receive his father's legacy.
Ok, now there's no need for this to be divided up like this- it makes it more difficult to read:
My favorite movie is 'Rain man'. The main character of the movie is managing a small company. His relationship with his father was bad. They had never met for over ten years. When his father died, he was notified that he could not receive his father's legacy.
Secondly, 'is managing' should be 'manages'. The second and third sentences don't connect very well, so why not join them:
The main character of the movie is the manager of a small company, whose relationship with his father was bad.
Lastly, how about 'would not receive'?
