Love films. Love producing Films.
The only thing I would add to Anthony's comment is that this tutorial video is called "Shooting a live event on a single camera." For the single shooter with only one camera, the entires series (which I watched) is full of great advice which would boost the quality of the finished product.
You bring up a good point. Using the same mic gets you closer to your production environment. I also think what the video pointed out is applicable: redo the entire scene. Nothing takes me out of a TV show faster than when one line of dialogue is ADR and the rest is the original.
I love how everyone bags on the BMPCC as not being a serious camera and someone turns around makes a feature film with it. For me, it's always been about finding the right tool for the right job at the right price-point.
I use a Western Digital MyBook Duo 4TB with my 15inch 2012 MBP using Raid1. This was certainly a HUGE step-up from the SSD over USB2. However it's not nearly as fast as comparable models at this price point.
I'm not sure I agree with the whole "editors know when not to cut" regarding these examples.
When we watch these films, Spielberg was under pressure to bring these films in under a small budget. Master Shots are the easiest, cheapest way to get your film in the can. When done correctly, the audience isn't even aware that it has happened.
