On the Subject of Real People's Accounts in this Weblog

I've been troubled by the fact that I must list real people's names on here for full account of my experience of film productions. I heard that "if you can't say anything nice, don't say at all" but... what should I do if I do have some critical perspectives that people won't like or misunderstand me? It's cowardly as a writer to think of a reader's wrath before he lays his words to achieve full effects, yet as a powerless beginner in the cut-throat industry, I need to kiss-ass, not know-it-all. I have a responsiblity to be faithful for all account as I'm chronicling my experience as well as filmmaking experience in 21st century. So for now, I'll play safe, and I may get bolder as I grow more confident and establish myself in the business. I'm not singling out out myself--on contrary I wish to be the harshest critic of my endevor, but I'm trying to be honest to my feeling and observations.
