I feel like with indie film we tend to accomplish things a few at the time, and build on that, as opposed to the studio mandate of a commercial ready project in x months. Each film is a learning experience, reinforcing what works, and making us more aware of which ideas sound better in your head than they look in the finished piece. I can't speak for this guy, but I've found that the time and resources most indies including myself have available to put into a single short film sort of preclude the possibility of a strong narrative. Squid game was about 10 hours. The plot was simple, and we only really got to know a half dozen characters. Try to imagine what that very basic plot would look like in a 4 minute version. Minute one, guy has gambling debts, agrees to enter death game, minute two, forms relationships with 8 people, minute 3, 8 rounds of games are played, and half the main characters die, minute four, the grand conspiracy and those behind it are revealed, including a surprise twist, escape attempt, boss battle, and epilogue. A single scene in that film would have as much time, and thousands of times the resources. Some would say, you know what, I think you could fit that plot into 4 minutes, and I'm sure they could. However, even with the same exact plot points, it wouldn't be good, because what made those plot points good was the way they orchestrated the ebb and flow of tension and interest over time, the one thing that short form filmmakers don't have.
I've seen it done a handful of times, where they were able to convey something particularly striking in just a few minutes, but in 99% of cases, you just try to really nail some aspect, perhaps to demonstrate to others the potential of a larger scale project that actually could support a story.
This may not be A Tale of Two Cities, but people are going to see this guys lighting, framing, and color work, and want to work with him on bigger things. I'm just guessing, but I'd say that's more the point of this piece than specifically telling a memorable story.
None of this is meant negatively towards the op or Spike, I'm just making some general observations about indie film projects.
