Screenwriting : What's the best way to get an agent? by Dominic Matich

There are a lot of schools of thought on this and I wanted to know everyone's opinions and/or success stories, or to hear from agents. I just graduated film school and wrote a 115 page called "Sharptop", a drama based on my true story. "A terminally ill teenage criminal looks to leave a life of crime and violence behind him in his final years, but after he's shot by a younger assassin, he chooses to follow a more deadly and mysterious path." I had an agent when I was younger, but he was a friend of the families, it didn't work out and I kinda was in the right place right time situation. Any thoughts?
