The third act of Human Revolution does honestly feel unfinished. There's no resolution to Jensen's investigation into his past, it just trails off. There's no conversation between Jensen and Reed.
Also, all those boss fights...the enemies are never explained or given personalities. They were cool and exactly the sort of enemies you should have been fighting all along (only way too hard to kill) and yet the only thing that makes them special is they have names. It'd be cool to know more about them.
A few other things...first off, it's stated that only Zhao and her personal guards are allowed on her floor. And yet there are offices there. WTF is that about. Also, you go to a secret base under Picus Montreal and there are offices. Enough fucking offices, damn it.
