I feel a lot of the nitpicking and digging comes from a frustration with the show’s overall structure. We are compelled to dig and examine and theorize about the characters, the show and the world because we know it won’t happen. We write sprawling, lengthy fanfics about the characters having long adventures because we know the show will never have anything like it. We draw porn because we’re a bunch of sick bastards =).
We do these things because we know the show will never do them, even though the show has all the right pieces. The characters, world, and themes of this show are phenomenal, but the structure of its production is borderline incompatible with the central thesis of the entire work. We see all that’s being wasted by limiting this material to self contained slice of life, with a rushed, similarly self contained adventure thrown in twice a season. So we pick up the pieces, and we try to let this material reach it’s fullest potential.
tl;dr We dig because we know the show won’t, and it would just be wasteful to leave it all buried. Our fandom is the fandom that will pierce Hasbro’s crappy marketing influenced show format!
