I got called Ghandi too, except I slaughtered everyone except for the captives.
So the Ghandi thing is default dialogue? That sucks. I remember in the first DX you got comments on whether you killed or didn't kill everyone on the island. I automatically assumed they did it here too.
The game is great, but I'm too much of a butt wipe to talk about what I like about it so I'll talk about what I don't like:
1) Story is too predictable, yet not really. Seems like there were no emails or messages that had anything to do with the main plot, just each respective level. Then again, there weren't really any huge twists for them to foreshadow. Or maybe it's because I was like 13 when I set my expectations by playing DX1 and was stupid, and now when I played DXHR I'm less stupid.
Haven't finished it yet so I can't comment, but so far so good for me. I don't know if I agree with the emails bit; perhaps you're right that in DX1 there were hints at a larger plot going on in the background when you read emails and personal messages. Then again, when I played DX1 the first time, though I wasn't 13 (must've been 18), I had no idea what to expect (story wise), so all plot twists and conspiracies were surprising and impressive. In DX:HR, the conspiracy angle is not only expected, we demand it. So I think it's hard to surprise us in general, plot wise.
2) It's too easy to just go around and kill everything. In the first game you had to be sneaky because of the way aiming worked. I'm not saying I wish they didn't change combat, I just wish they found a better way to do it. Then again, it is pretty neat to just be able to fearlessly walk through laser alarms and by cameras because you literally already killed everyone that would hurt you. Also the last level with the heavy rifle = 
I think this counts as a good thing. I think in DX1 you were supposed to be able to do this, but the controls didn't allow it. Also, in DX:HR, before you invest in damage reduction augmentations, combat against multiple enemies is rather hard as well (at least for me on medium difficulty).
3) Level design really hasn't gotten less cramped further into the game. I'm going to chalk this up to memory limitations because they still did seem to have reasonable amounts ways to do things, it just seems odd that the doors/windows that just happen to be unlocked/hackable also just happen to be the ones that provide better routes to your objectives. Still, I could just not be seeing things. Maybe I'll enlighten myself on future playthroughs, which there will doubtlessly be.
I dunno if you missed anything, but I think the level design is extremely similar to the first. There's always at least 3 ways for getting things done from the following approaches:
hacking, killing, punching through wall, disabling cameras, finding key-code, crawling through vents.
Though I know what you mean that the story doors and computers are always easier to hack, but that's a reasonable design choice isn't it? If you have to hack a computer for the story to progress, it has to be level 1; the game can't force you to invest in hacking augs.
4) Killing people. I shot Tong like 4 times in the head with a revolver first time I saw him and he didn't even flinch. In DX1 if you tried that on Manderley at least he'd go rambo and kill you, but this is just boring.
That IS weird. You would expect nearby guards to at least jump you with everything they got. :\ Haven't tried anything like this. I usually leave stuff like this to subsequent playthroughs. I always enjoy the first one "properly"

Hacking Bloooooooooows. 
Strange. I even hack stuff I don't have to because I enjoy it so much!
