I should be the last person defending them, but people need to lay off the EGM hate. They gave DR a 7.5, which is still great in my book, considering they need to factor in length, lack of multiplayer, the save system, etc... Not everyone is going to have problems with these things, but they're still issues that EGM needs to point out for the people who will. Just enjoy the demo, and throw review scores to the wind.
Since you're controlling the camera most of the time with the right stick, left stick aiming makes no sense, but I've already adjusted to it. It's just a bit awkward.
