Lots of people want to write for TV or film and there are lots of platforms, services, contests, etc to help would-be and current writers. Stage 32 stands head and shoulders above the rest. Here are my personal observations why based on using their services over several years.
The craft of screenwriting is important -- Stage 32 provides access to industry reviewers to look at scripts as well as very well done how-to webinars (live and a great archive library). Since those are done by industry pros, the feedback is useful and cutting edge.
I find the greatest value however is the emphasis on understanding the industry. It doesn't matter that you have written the greatest script, if you can't get anyone to look at it, let along produce it. The Writers' Room of Stage 32 brings in industry executives who share their experiences on their journey to success. As the CEO RB Botto keeps repeating, you have to understand how the entertainment industry works to be successful.
Stage 32, and especially its Writer's Room, helps you improve your craft and understand how to sell your product. It's a winning combination.
