navigation - Are Drop-Down Menus Outdated and Poor Practice?

I have read sentiments online about the demerits of the trusty drop-down menu.

EDIT: By 'drop-down menu' I refer to the navigation bar on a home page, not a drop down list on a form.

Is it really bad for SEO? More importantly, is it bad UX? Is it time to consider an alternative navigation option, and if so, what would you suggest?
