Industrial Scripts are becoming a de facto part of my development cycle. This is the best endorsement I can give, and one that should ring bells with anyone serious about development with regard to their work, and consequently a potential screenwriting career. With development time at a premium, it's critical to focus energies in the right places. It's crucial to know those places, and people who can help you identify them. The development marketplace is awash with self-monikored development gurus with no credentials (these can have a negative effect on your work / career / professional reputation). In this regard it is becoming a marketplace skill to get feedback from the right people, more than ever. If you're ready for honest, marketplace-aligned, constructive criticism of your screenplay (if you aren't, you should be), you can do a lot, lot worse than Industrial Scripts.
