Observations of unusual metallic behaviour in the vicinity of quantum critical points are now numerous, and many are by now decades old. The traditional theory of such phenomena, Hertz-Millis-Moriya theory, turns out to have problems, and in the past ten years there has been a surge of efforts to build more complete and consistent theories along newer lines. In this talk, I shall explain what makes this problem difficult, and give an overview of the work in my group [1-4] - past and present - to try and improve our understanding of these unusual phases of quantum matter.
