See. Terrible criticism. See the difference ?
believe it or not encouraging you to write a script is some of the most helpful criticism you can receive.
i think you are quite confused if you believe that is terrible criticism. I tried to make an analogy for you to see the error of your ways but maybe its hopeless ?
I will make one more attempt to reach you.
There is a common expression in the industry ... writing is rewriting.
What this means is that scripts are never done on the first draft.
Why? Because Criticizing stuff is a lot easier than creating stuff.
So first you write something.
Then you read it and criticize it.
Then you rewrite it and its even better.
This process can repeat and the script keeps getting better every time.
You film version 4 of your script this way. If you just go in and improvise youre only going to film version 1 of your script.
if you write it and then rewrite it the movie will be even better. probably a lottttt better.
