5/10 or average.
I thought the campaign was fun. Only problem with the campaign is that it tries to one up Call of Duty 4 too much.
As for the multiplayer, it's fun, but like a greasy cheese burger. You know it's unhealthy for your heart, but you still eat it anyways. And the aroma of salty fried food keeps you coming back for more. The multiplayer is plagued by glitches and unbalanced game mechanics.
Was the a bad analogy?
