I would say:

metal but with less cool guitar solo's, more riffs that everybody likes and not all that chaotic.
ohyeah, sometimes nu-metal uses weird vocals, you know uhm the boyband kinda like vocals, It's metal but in a diffrent way, more uhm accesable or something?

however there are some cool bands that are considered nu-metal but are cool, like Agrésion, Locomotiv and Dimesion Seven, those are cool bands but are classified nu-metal, maybe cuz of their early cd's. don't know.
