Just came back from dragging my mother to see Captain Marvel again to get the senior citizen discount they have on Tuesdays. Don't judge (yet). [Mom's response: "Next time I'm choosing the movie".]
I watched it and I loved it. I liked it a lot more than Wonder Woman because it didn't hit my trigger point of someone needing important information and the people who are supposed to help don't give enough information.
Speaking of information, a big part of why I went to see it again (other than it's a really, really fun movie), is that I needed to figure out how Carol got to that file so quickly. So yes, I was mostly focused on reading the records signage and trying to understand the classification system during the fight scene. (You may judge me now).
Initial thoughts: it looks like - at least the part of the department where Carol and Fury went to - it's simply personnel records, arranged alphabetically by last name (which is the answer to "how Carol found that file so soon if it's an archive"). There's signage for the letters (BD-CA, for example. With some numbers underneath it, I have no idea why but bear with me for a second here). Given the size, if it's only personnel records, this has to be the files for really, really lots of people (I'd hate to guess, but really, lots of people) over decades. The problem, of course, is that almost no one will spend money of expensive archive materials to preserve personnel files for decades. Organizations shred them after a while, and not a lot of things are stored like this for decades. If the information is needed, it will be converted to other mediums (hi, computer files and reels!).
From these assumptions I got two options: 1. This is not only used for storing personnel records. Makes lots of sense, but doesn't correlate with the classification system. Unless the numbers underneath the letters also mean something (that the person in charge of this part of the script had partial understanding of relative location/index), so more information needed there. 2. If it's only personnel records, stored for decades in expansive and ineffective preservation system (because it's not an archive. We don't organize archives alphabetically)... then U.S. air-force, who are you exactly cooperating with and to what end, that is my question.
(OK, I'm done for now. Other information science issues in the MCU will be discussed after I will get enough sleep).
