First impressions of 4 hours or so are that it seems a sort of half-hearted effort. Less put into the story, less focused in level design, less variety in baddies, and a more padded out pacing (it took me 2 hours to hit a boss fight). All of which combines to make a rather tedious early experience, especially if you already played Dark Souls and don't need the practice/training.
A certain amount of polish seems to be missing, I'm getting some minor headaches from texture pops on PS3, and its not like they're throwing uber-HD textures at it or anything. NPC's are lifelessly barely animated (if at all). Maybe its cause the more 'open wilderness' doesn't suit it, but it seems like there's a lot less hidden secrets and stashes about.
The story also seems totally directionless, thus far its "You are cursed, so you went to this place, cause reasons. Now you have to see the king, so go find the 4 things wherever.". Compared to the two bells in Dark Souls, which they gave you some vague direction to aim in, and a general (if vague) purpose to what you were doing. They try and put a lot of impetus on "You must do this, or become an insane starving Hollow undead", but there's nothing remotely pushing that tension ingame.
