Is it written correctly?

Hi, I have the next homework:

An email: My favourite film

Write an email to your English friend. In your email, tell your friend about your favorite film. What kind of film is it? What is it about? Do you think your friend would like the film? For this task, you should enter between 50 and 90 words.

That's what I've written:

Dear John, I hope you are doing great. If you don't mind I am going to write down a couple words on my favourite film Goodfellas.

It's a criminal drama about a guy called Henry Hill. A story begins with his childhood where he is so naive and young. Living in an Italian ghetto Henry someday meets syndicate that purposes him a simple job - serving the Mob's needs. After a while, he realizes that he always wanted to be a gangster..... I hope I've drawn you into the story.

Huge thanks in advance!
