I would agree with the score of 9.
Just finished the singleplayer and it was good. Not as good as Goldeneye. I dont think a few bits of missing content really would change my opinion of it.
Multiplayer is where the game shines. Its really well balanced. Loads of content. Solid controls.
For the record I have never had any issues with connectivity. As stated before, Treyarch is giving far more attention to the Wii than most 3rd parties. BOwii is a vast improvement over the previous games. And they put most of the content that you get in HD versions.
It is an AMAZING game.
