But again, to be fair, there have been plenty of games anyone could claim fit that description that I have thoroughly enjoyed.  Take EA's Dead Space for example.  That game did very little original, but in the end it was a tight and well executed experience.  I feel Killzone comes up short in this regard as it feels so forced and tangibly predetermined to deliver what is ultimately a known quantity - which again, isn't necessarily a bad thing - but given it's development time and production values, I was hoping for a more gratifying experience.  This is not to say that Killzone 2 has no redeemable qualities.  It's campaign is pretty well developed, the visuals are stunning, the gunplay is decent despite the controls being reminiscent of someone playing doom in a pool of jello, and the multiplayer is genuinely fun.  But again, I can't shake the slightly dirty feeling of playing a game so focused on being everything that sells, it becomes more of an advertisement than an interactive experience.  Does that make it any less satisfying for those who enjoy it?  Of course not.  But there is a reason why I don't watch television anymore, and that same reason left me not enjoying my time with Killzone 2.
