The flaws are hard to notice, and if you aren't a professional CG artist I can't even imagine being able to spot visual mistakes while in the middle of playing the game. Killzone 2 looks spectacular for a game I'll never consider playing. :p
Really, it looks great. Maybe you can do a little more on a PC, but I'll be damned if anyone can tell without screenshots or years of training.
You do not have the right to never be offended.
