I use Final Draft also!
Warning, I'm going to go on a rant...
- BUT I HATE that it's called the industry standard. The industry standard is PDF - You don't get sent scripts in FDX format EVER. Maybe, if you are on something really low budget where the writer isn't willing to do small revisions you will get an FDX, I have as an AD asked for the FDX so I can do proper colored revisions, but that was a rare circumstance. I have never been given the FDX file of any script for any movie or TV show I have worked on. John August and Craig Mazen of scriptnotes have an episode of their podcast but the way Final Draft markets themselves this way and how insane it drives them. If I didn't already own Final Draft (and I am not upgrading to 10) I would be using the software John August created, called Highland, it's based on Fountain. That said.... Final Draft is compatible with Windows whereas other programs are not. Although I know very few people in the industry who have Windows computers (except editors).
Best bet is to buy The Hollywood Standard 2nd Ed formatting book - Think of it as the MLA handbook for screenwriting. You should learn/know the formatting style by memory as best as you can and the software should support/supplement that knowledge, not be a substitute for it. That's a whole other rant from when I was an AD on projects that had typos and formatting errors all over them. It was embarrassing, even though it wasn't my script.
To rebuttal your point, I don't think it's called "the industry standard" because everyone shares their material as that type of file. It's the industry standard because a lot of (but certainly not all) "professional" screenwriters USE the software to write. Of course they don't share their finished product as a FDX file — it's never smart to send something in a specialized file format, regardless of industry. You simply convert it to PDF (which Final Draft does pretty easily) so it's easier for people to access it. It's the difference between sharing a PNG rather than a PSD for Photoshop. Yes designers OVERWHELMINGLY use Photoshop for graphic creation, but they wouldn't share it in the format — you would chose something that's easily accessed by all.
TLDR: The "industry standard" in this case applies more to what people use to write the script, rather than what format people use to share it. After all, you can't write a script in PDF format. But you can share it afterwards that way, which pretty much everyone does.
Your final point definetly remains though — presentation is important, and you should have a working knowledge of how things should look. That said, why go through the trouble of formatting yourself if a program can do a good chuck of the work for you? From experience, the writers who think they can just create a script template through Word because they "know the format" almost always look off.
