I can see how it could be irritating but I actually liked it once I'd gotten used to it. I think it just encouages one to play more cautiously, and I feel makes the game a bit more tense, because the camera angles (combined with the no-show of the radar system) leave you feeling a bit more vulnerable. And, you can swoop them 'round a bit with the right anolouge stick.

So, I actually liked the camera system. Thought it made the sneaking more "edgy" or something.
