Amen, Mario.
Along this topic, there is one thing that I really gets to me.
Granted, there are too many people these days who are fascinated and even obsessed with the idea or wealth and fame, and the glamour that they see radiating off of Hollywood and the movie industry, and so many people are "jumping on the band wagon" and swearing that they will be famous and they've "got what it takes". (Just look at American Idol.) Truth be told; not many of them have what it takes, not many at all. Some of those who believe themselves to be the next Speilburg are, in fact, the clueless ones, though they believe with all their heart that someday, it will work out for them.
So, at places like Triggerstreet and AW, we run into all those different "types" of writers who, incidentally, are the ones who critique us when we share our work.
What bothers me about this is that, though some are the "good writers" who really do know their stuff, too many are actually the "clueless" ones. Tarantino himself could post the first ten pages, and other forum members would rip him apart and tell him that the work just isn't good enough.
This has caused me a lot of problems because there are so many opinions and ideals pulling my writing in so many directions, critiquing it (even though they may not be giving me valuable or even relevant suggestions) and judging it with a not-so-pro opinion that, now, when I sit down to write, all I can think of is how "wrong" everything is going to be.
Bottom line; I think that a writer needs to get the technical information, the how-tos and what-not-to-do's, and just move on. It all goes back to the fact that you CANNOT please everyone, all of the time. No matter how good the work is, no matter how well it could actually do in the hands of Hollywood players, you'd never know as long as you have board users telling you that they think everything about it is wrong/not interesting/blah blah blah.
