With modern dubstep and its variants you're usually listening to something borderline annoying and/or repetitive being manipulated, cut, and dragged out seemingly with a vengeance until it becomes this solid WUUUB WUB WUB WUB sound and that can be refreshing in a way. Also, it's generally somewhat erratic, confident, energetic, and almost otherworldly, and some people at least find that pleasurably distracting rather than irritating. It also still has the novelty appeal.
