I've been giving screenwriting notes for over seven years! Through my experiences with both the notes I've received and the ones I provide, I've discovered that the best feedback is tailored to your intentions and what you aim to achieve with your story.
We've all encountered script feedback that says things like "this just isn't working," "your main character is thin," or "your structure is off." Often, it leaves you to decipher what's wrong. While that's part of the business, imagine receiving writing consultations from someone who truly understands your vision and takes the time to give you insights that align with your goals. You'd likely spend less time wondering, "what did they mean by that?" and end up with a stronger next draft.
