I really don't see what's supposed to be good about Dark Souls besides difficulty. The games looks reeeeeeeaaaaally boring.
It probably is. Just like Demon's Souls, navigate narrow corridors for hours and make sure not to get hit once by anything, or else you have to do it all over again, AND loose all your souls(xp).
Not to mention the confined areas that makes Doom look like a freeroam openworld game. REALLY depressing
