I think part of the problem may stem from having no real interest in the protagonist; I honestly can't even remember his name for most of the comic (he later finds out his real name is Nick Fury Jr). There's a basic set-up involving a history of college football and time in Afghanistan, fighting with the Army Rangers, but before the reader can blink, Fury Jr's mother is dead and he's fighting Russian mercenaries until Cap, Daisy and SHIELD pull his arse out of the fire. From then on, the story lurches from action scene to action scene with no real pause or joining narrative; the whole thing plays like a trashy action film where pace replaces character and motivation.
The end result, however, seems worth the rough road getting there. MCU SHIELD is active in 616 and an adaptation of an adaptation of Ultimate Nick Fury is up and running alongside the classic versions of all your favorite Marvel super heroes. All I'm saying is, maybe skip reading Battle Scars and just read the wiki or digest to get the story. Hey, if you can handle the idea of radiation giving people super-powers and fungus people living in the core of the Earth, then SLJ turning up to be the new Nick Fury isn't too big a deal.
