Sorry, it was more of an exasperated wail haha.
But it's really emblematic of a more pressing problem with Metal.
That being that Snyder is injecting the Metal everywhere
. I know it can be cool to create long unexpected connections between properties and concepts in comics - but they have to make sense. In Metal's prologues the Metal is apparently everything.
Melted lazarus pits, Wondy's gauntlets, Aquaman's trident, Shazam's dagger - it's connected to Hell, Heaven, the dreamscape, Uncle Sam!
The midichlorian thing just really underlines how ridiculous it is getting because meta has a real life definition - it means "beyond" - but now it's just "oops four letters" and apparently metal can be genetic.
That's why written records exist. Especially back then when they were immensely more common. And it also brings up the question as to why the Doctor never clarified any of this.
Also, that's abbreviations exist - if you were gonna abbreviate "Metal" - why not go with "MTL"?
