You just get it, that's exactly what most people have been complaining about regarding gameplay. DMC3 is the only game I've played in the genre (does Bloodrayne 2 count?) and I've never been too good in it, but it was so rewarding when I could get SSS after much effort. It was the greatest feeling. And I knew I deserved it. DmC is just too simple and easy, even for the casual player. That's why it feels unrewarding, even though it showers you with SSS. It totally destroys any incentive I might have to replay the levels or even play the next one.
But anyway. Can't wait for part 2!
