I took Lucy's advice about "the power of three" and I have three people from one message board reading my script, and three from another board reading it.
Here's the first bit of feedback I got today from one who is a film student. She warned me yesterday when she agreed to read my script: "I can be very mean sometimes when I critique people's work."
Anyway, here's the very opening line of the PM she sent me just an hour ago:
Wow, wow, wow wowowowowowowowowowow... and wow...This is incredible almost. I'm only on page 97 ... and it is truly amazing.
This is very encouraging. I can't wait for the other responses. This is so exciting!!
