Seems to me like everyone is complaining about the poor boss design of multiple enemies in a battle. It's even worse in NG+ with added enemies to a couple of bosses. The other complaint is that all the bosses are easy except for the one hit kill bosses that are cheap. Gotcha deaths are all about paying attention to your surroundings and reading the messages on the ground. The tension of death around every corner is what makes the atmosphere. Variety to the deaths helps a lot.
I also started deprived and that dagger is so terrible, but you know what you're getting into starting with no gear. I tried killing that first ogre with no equipment and my fists, just because I knew it was possible.
That came up in an old Bombcast as Vinny was describing Dark Souls (Oct 2011 I think). He was on beams and then was killed by a hidden enemy. Conclusion? Stupidly frustrating. Still there were probably messages warning about that threat. I think a lot of reviewers (and by extension the average game playing audience) just had to unlearn a lot of their habits of rushing into gameplay, clicking through text.
