When something is great, say it's great. Uncharted 2: Among Thieves is indeed great. Sometimes the best in entertainment, whether it be music, movies, or gaming, are never experienced by the masses. They slip in and out and the ones who had the privilege to enjoy the genius deem themselves as blessed.
Uncharted 2 is an exception. It is one of the most amazing and memorable gaming experiences ever forged, and it's being enjoyed by millions, over 3.5 million actually.
