I think the implementation of a "score" is the big fault of this game. Like you said before in this thread, it gives you negative points for playing it "wrong" and therefore is discouraging you from the experimentation that made Blood Money and the other games in the series so awesome.
Totally, I really hate the way the game has been dissected like that, any illusion is thrown away because of it. I only got this impresson from the QL so I have no idea if you can turn it off and ignore it or not.
Another small thing again from the QL, is that it might as well be Hitman: Arkham City. I remember Hitman games of old having some really vibrant colourful levels as well as dark ones naturally, but everything I have ever seen of this games looks far far too brooding. I'm sure that is the direction they wanted to take it in but I'm not such a fan of that in the context of Hitman.
