Demon's Souls is the best dungeon crawler I've played since diablo, though it's more reminiscent of even older WRPG... ones I can't even remember the names of because people don't talk about them much any more :)
It scares you and puts you on your toes by punishing you for dying, but never punishes you too much. It has traps AND single non-boss monsters that will make you sweat when you're first exploring a level, and the level design itself is very satisfying. And I'm having a blast with the multiplayer, co-op and pvp.
Tried the demo of Ninja Blade and thought it was pretty fun too, though I've got enough action games I have to finish to pick that one up right now. Some of the monsters seemed very Demon's Souls-y, and it was cool how they were transposed to a big modern city.
