Does that make me a great writer?

No.

Does it entitle me to pass judgment on your writing?

Not necessarily.

Would my opinions and analysis improve your script?

Without a doubt. Those companies wouldn't have paid me if they didn't think the scripts were professionally written and worth paying for.

I could mention five other projects I have been hired to write for production companies – one was a feature that was never produced, three were treatments for a German company that were never produced and one was a feature for a New York-based production company that was produced. I was also an associate producer on that project.

Additionally, I worked as a reader for a year, for Vidmark, Open City Entertainment and Landmark Productions, during the course of which I read a few hundred scripts too many of which were disgusting and/or psychotic or merely boring, pointless and unintelligible.

Maybe 5 out of a 100 scripts I read at Vidmark, Open City Entertainment or Landmark Productions were not automatic passes. Of those 5, maybe 1 or 2 were good enough to pass along with a moderate or better recommendation.

I have been paid for newspaper articles, public service announcements, and personal letters written for people who weren't skilled at putting words down on paper. I have been paid for content written for websites. I have written one and half novels I haven't been paid for and am currently halfway through a non-fiction book on autism that I will be paid for. I have made a living as a result of my reading and writing. Along the way I have thought about scripts and screenwriters a lot. And what I think is:

Most writers won't tell you their work is all-but-ready for display in the Academy of Motion Picture Arts & Science Hall of Fame but ... a lot of them think it might be.

Most writers think of their second draft as the "polish." I'll say this: my last optioned project, the Samual Jackson movie, was a spec script that we have at least 50 drafts of, only about 20 of which had significant re-working in them.

Writing screenplays is tough. Very tough. A structural overview is critical to successful screenwriting and it is the hardest thing to come by for most writers, despite the large amounts of time they spend hunched over their paperpads and keyboards in libraries, coffee shops and living rooms across the planet.
