Does anyone have a favorite diff tool for reviewing lots of code? I'm thinking something along the lines like meld or vimdiff. I don't really need a git client. I'm comfortable with the git CLI. I'm mainly interested in making code reviews a little easier to manage.

I'm reviewing a large code change right now and the web interface sucks. It's slow. It doesn't load all the files at once. Cross referencing files sucks.

I know, I know. "Code changes should be small." I've already voiced that to my team, yet here we are. I'm trying to figure out a way to make this a little less miserable.
