Eh...I wasn't one of them who praised it. The whole idea of a moveable camera irked me, because if I felt the need to zoom in on the face of every single unit, I'd play an RPG instead. But since I'm supposed to be commanding an army, the more I can see on my screen at once, the better.
Don't get me wrong though, it's a nice idea, but I think it's just not implemented in a good way. It's flashy, but not really useful. I think that's what Blizzard is going for in SC2: Focusing more on graphics and less on gameplay. But, that's just what it LOOKS like. Won't actually know until the game comes out.
