Go replay ME2 and really pay attention this time. This whole series went off the rails storywise in the first few minutes of that game when they killed off and resurrected Shepard for no conceivable reason other than to force him to work for TIM/Cerberus. You remember Cerberus from ME, right? Somehow we're expected to believe that a small group of former Alliance black-ops goofballs transform into a near galactic superpower with seemingly unlimited funding and a private army. It's beyond wretched how incompetent Mac Walters is at crafting a coherent narrative.
I never played the first ME (PS3 owner here), but I figured that they'd have at least have a few nods in the comic prequel thing. I can't recall them even being mentioned, much less discussed at the status they appear to be in ME2. Then, somehow, they get so powerful that a human fleet is required to take down their main base. Just doesn't make any sense. Not significant enough to discuss in the scope of the story for the first game to acquiring enough resources and recruits to attack the citadel, multiple human colonies, and require a whole fleet to take them down. In a year or so. And somehow having the tools to indoctrinate their own soldiers. Yet not really since they don't work for the reapers.
Just illogical.
