When Steven Spielberg first worked with Michael Kahn, he asked him about a particular edit, "Why did you cut it that way?", and Kahn said, "Because it felt right." Spielberg thought that was the best answer he'd ever heard. To me, 99 percent of editing boils down to that. Does it feel right? Murch's rules are nice, are well thought out, and if you're writing a book about editing I guess you have to come up with something. But I almost never edit while thinking about these rules. It's all gut feeling, emotions and hard earned experience.
I also looked at films in wide release a while back and found the average age of the director to be around 44 years old.
The Film Convert plugins are nice, but are very render intensive. If you're on FCP X, the built in Super 8mm filter actually does a pretty good job for this and it's free. There are sliders you can use on the filter to dial in the amount of grain and vintage colouring you want. And it plays in realtime on any decent system.
Dynamic range and color science are more important than resolution when it comes to digital image capture, one reason the Alexa is so popular with cinematographers despite it having barely more than 2k resolution up until recently.
The opening paragraph mentions the relentless bullying she's faced online, so it's not a misplaced comment...I do agree Finn is not a well used character. I found it odd they continue to separate Finn and Poe when in their brief time together in Force Awakens they had great chemistry, and a clear character conflict. One wants to fight, one wants to run, but they are stuck together. In Last Jedi, again, they separated the two characters for some reason.
Yes, don't blame the Asian girl, blame the black guy. That will keep the toxic racists on social media in line.
