This nails (some of) what's wrong with Mankind Divided's narrative.
Everyone talks about how it's half of a plot, and it is. But it's also a bad half of a plot. So much exposition. All tell, no show. Talk talk talk. Dense, obscure motivations. No characters I care about.
Deus Ex (the first one) and Human Revolution both had intricate, densely plotted conspiracies as a backdrop but ultimately the characters and their motivations were simple. My brother is a double agent. Is he right or not? My girlfriend is missing. Can I save her?
What motivates the main characters in Mankind Divided? I'm a...counterterrorism beat cop... and I'm talking to a group of hackers...because, who knows, reasons, I seem pretty apathetic about the whole thing. There's a bombing and a frame-up also because of reasons, it's not clear how it relates to me. There's a cutaway to some old men in a room and it's suggested that they're manipulating me, but I'm never shown any manipulation or any impact on my life at all for that matter.
It's a really terrible, broken execution of whatever story they were trying to tell.
