I have found an interesting blog entry at Blake Snyder’s webpage. It is about the criticism he gives and why. Although most writers want to hear him say that their script or pitch is perfect, he points out that questions and criticism is fertile and leads to development.

I agree with Blake Snyder. Criticism can be fuel to very creative work. It will probably take a while to learn to handle criticism, but it is a skill worth learning. Nowadays I find criticism honestly inspiring (once I have past the first chock that my script was not perfect, which takes me by surprise every time).
You may not agree with the criticism but the least you could do is to ask yourself why the reader pointed out those particular things. If the reader misunderstood the story completely, maybe you are the one that have not been clear enough in your writing.
If you don’t listen to what your readers say then your script will probably never become a movie. The only way to know if your vision is there on paper is to listen to the criticism.
I don’t say that you should do every change every reader suggests. Then you will end up with a script that is probably worse than the one you started with and it will no longer feel like your story. You must listen to your own heart too.
Once upon a time I got criticism from a guy who succeeded to get my story out of track completely. He probably saw another story than I indented, but I didn’t realize that so I made the changes he suggested. The result was a lost of focus on the main character. It had moved to my supporting character, which he liked better.
What I should have done is asking myself why he liked my supporting character and not my main character. This might have resulted in something useful. Maybe I had added features to my main character, maybe removed others from my supporting character, who knows.
