Two guys logically explain why The Boss, a middle-aged war veteran, does not look like a 20-year-old e-girl
Gamers: Well she should look like one anyway
I'm so tired 
It's so fucking stupid, she looks pretty much exactly like the original character but in a photo-realistic style
Holy shit, I somehow missed the most unhinged comment:
[CW: Transphobia]
spoiler
They made the boss look trans and that's a fucking crime.
The chin is different, it looks like a man's chin, the mouth is different, it looks like a man's mouth, more specifically it looks like Chris Chan's mouth, don't believe me, go do an image search. Neither the mouth or the chin or the brow or forehead or zygomatic process feminine in any way in the remake version.
The boss has deep cheek hollows because they changed her maxilla as well, literally everything they did was to make the Boss look like a ******.
Their brains are so fucking cooked
There's definitely some sexuality undertones in The Boss vs. Big Boss, especially in that last fight where she's in a skintight sneaking suit half open to show booba. That's definitely intentional, she spends her the entire game in very much "unflattering" but very practical clothing.
They're basically fuckfighting to the death at the end there.
It's a
production, so it's naturally going to be a bit weird and horny (and oedipal in this case) - just not completely porn brained like the gamers are.
All Kojima games have their moments of being weirdly horny for little else than fanservice, but they also tend to include moments that are kind of horny with actual message and the whole thing about The Boss is that that's there as much on purpose as EVA is trying to ride some solid snake
