Despite its name, Xbox 360 Fanboy somehow finds it odd that they can't find much wrong with Halo 3:

I never intended to write a review filled with nothing but praise for Halo 3, but it's just damned hard to criticize. Sure, there are things I could point out that are disappointing. The graphics aren't perfect. You can't save clips in campaign. The story will be confusing to newcomers. Yeah, I can pick nits all day if I wanted to, and doubtless many Halo detractors will do just that, but the game is good.

Halo 3 is good. Glad that's cleared up.
