For your next piece:
With the dialog beginning almost immediately there's little opportunity to get caught up to speed on what's going on. Even a few more seconds of scene intro before dialog begins would be useful to the audience.
The trombones blare at parity with the canny/cheap speakers VO dialog, which I like very much as a nice effect, masking much of the appreciation for the story.
Two approaches:
- 1. Knock down the whole soundtrack-to-dialog to a minimum of a 40/60 split, my preference is 30/70.
- 2. Manually face the soundtrack in and out/up and down to accommodate sparse patched of dialog. Obviously that's more time and labor and runs the risk of creating a warbling soundtrack wave effect, but maybe if used conservatively...
Don't know what criteria/audience limitations were placed, but choking a person unconscious or dead goes much more graphically than shown @ 3:29. Even a suggested choking out of frame goes worse. For time considerations... I dunno. For suggesting a real choking... I dunno. I'm just grunting and pointing. Sorry.
Regarding hanging the audience for more, could have shown the black hat & coat suit man as an executive employee at the facility now faced with a dilemma: Compassion for subject or Conviction of greater good. Classic means to an end, desperate times call for desperate measures sorta stuff.
Make the story follow the test subject - and - the voice recorder, the latter being a tool to drag more characters into the story as it's weaved complexity becomes more evident.
Perhaps the injured, (now dead?) paper-suit transporter has a personal or professional relationship to the black suit.
Maybe there's a whole other story going on.
Maybe black suit lets her go. Then finds out she killed his paper suit brother.
Maybe the paper suit was injured saving black suit the night before and now black suit is after her.
Maybe paper suit thought he killed black suit last night in a workplace coup attempt and now he's set her free.
Cut down on the dragging elsewhere to step up the complexity with the same characters in the same time footprint.
The languishing pace nears sophomoric drama hyperbole.
Don't be afraid to demand a bit more from your audience.
