Killzone 2 aim/look speed: Realism? Or bad attempt at it?

[Cidien]

I should probably state that the controls aren't the reason I won't be buying KZ2.  The poor aiming mechanic will impact sales, but its the lack of coop that keeps me from a purchase.  I don't like the MP enough to spend $60 on it, and there aren't a whole lotta shooters I enjoy playing solo nowadays.
