I think there's a good way to tear somebody's script apart, and a bad way.
There are some people who kind of just enjoy tearing shit apart, and are almost mean about it. It's like they're trying to demoralize you.
Then, there are those people who genuinely want to help. These are the people who earn the title of providing "constructive" criticism. In addition to pointing out the flaws, they will also point to the strengths, and they will add encouragement, while suggesting which things they might consider changing. I believe this type of criticism is very healthy, and helpful, and I feel like my movie is considerably better for it, because I sought out as many people as I could find (local, and online), and asked them to be brutally honest. Obviously I hoped they wouldn't be dicks about it, but I wanted to know their honest opinions, and I'm eternally grateful for this.
BINGO!
