What I liked
This internship gives you the opportunity to work alongside the developers and creatives involved with pre-production of content destined for Netflix and Hulu. While not necessarily being a direct link to employment to these major companies (nor should you expect that) this internship gives you the opportunity to develop real screenplays, write coverage reports, and talk to the internship provider about key issues and what he would professionally be looking for when talking with writers and producers. He has invaluable insight.
He is highly informed about the craft of screenwriting and his previous work teaching screenwriting at Columbia College definitely comes through with his approach to this internship. This internship will be valued by those of all skill levels and it is a very comfortable and learned environment to practice script reading, consulting, and development. You won't necessarily become a great screenwriter from this internship, but it doesn't advertise that, it advertises screenplay development and it delivers. While the industry is tough, this internship shelters you from an typical egoic boss, gives you access to all his educated opinions and contacts and most of all he values you way more than, really, a script reader and developer should be valued at this level. You are working with him, not for him, and for that reason this internship gives you more opportunities and room to connect with the industry if you ask for them.
