I just beat the game last night.
A few things bothered me, but I would give it a 9/10.
The Bad: It was plagued at times, as Uncharted was, by predictable and completely unrealistic things, as well as the amount of gun battles/sneaking. The world was literally set up like a paintball field at times
. The lack of craft able weapons was kind of annoying, but alas, still fun.
The Good: The game is beautiful from start to finish. Weapon mechanics were awesome, and there was enough gun selection that it never got stale. The length was pretty much perfect. The separation of the game into seasons provided a good segue between cutscenes. The story was Hollywood quality from start to finish, and the connection and growth between Joel and Ellie, and the connection between them and those they encountered was very palpable. You actually grew to like the characters.
