Check out Reviewable, it's influenced by my fond memories of Critique but designed specifically for git (and GitHub).

Reviewable is amazing, thanks for making that.

I've used lots of review tools and worked a bit on Google's review tool and on ReviewBoard in the past, and Reviewable is better than all of them in my opinion (or at least, better than when I last used the others).
