Thought Dark/Demon's Souls were pretty good with the darkness. Pretty much all dark areas you were able to see well IMO, and in a place like Tomb of the Giants in Dark Souls it was intentionally really dark, so you just needed a light source and it's fine afterwards. I also like how obtainable items in the Souls games are really bright, so no random walking into the darkness to see if I can find anything. You can usually tell where it is well enough.
The puke filter in Blighttown makes it far too difficult to see what's going on. Seeing it spring into place as you cross the threshold from the Depths or the Valley (or removed on the way back) is also jarring. Then again, the whole game is too dark if you follow the in-game brightness guideline.
Dragon's Dogma is cool with the darkness. It's really dark at night, and it makes the game give off a different kind of atmosphere. Lanterns help, but you still have to be a bit mindful of where you're going, especially since the world is big. The game will tell you that it's dangerous at night but I haven't really found that to be the case yet though lol.
DD does darkness right -- the lantern lights up a reasonable area to a reasonable level of clarity and brightness, while the area outside of the latern's influence is entirely dark. There's no need to fiddle with your display's brightness settings.
