I bought this book years ago when I was in film school, and I'll be honest I didn't use it as much until after I graduated because I started working immensely on my scripts. It has helped abundantly! Incredibly encouraging style! Yes, it is hefty in size (over 400 pages) but it's worth the amount and time to read. All the advice and structure helps with different aspects of the industry, from formatting spec scripts, query letters, tips on dialogue, it's incredible! Without being overbearing, it's well organized.I recently found out about the 7th edition so I also have that for informational and new industry standard comparisons. So far it seems to be a bit more condensed in certain chapters compared to the 6th but overall still hefty. Some paragraphs are removed for clarity, some are added. I prefer the 6th in some ways because of the organization but both are fantastic. Also, the order of the table of contents is rearranged a little in the 7th edition.
