Indeed. The only reason to still consider certain parts of the Middle Ages as "dark", particularity the early portion, is the due to the lack of contemporary sources. The Merovingian Kingdoms of the seventh century, for example, are genuinely hard to study because we've lost so much.

The term "dark" should not be used, as it still much too frequently is, as some negative value judgment that covers a thousand year period which encompassed hundreds of different societies and cultures spanning an entire continent.

It is understandable why people think this way, since European history (at least in the United States and Canada) is still largely taught in a way that skims over the Middle Ages: check out how awesome Greece and Rome were, then, well, the Middle Ages when they had these grand churches, but who cares because then came the Renaissance when everything was cool again.

I've taught European Medieval history survey courses at the university level and one of the most difficult challenges was getting this idea of a horrible "dark" age dispelled from the students' minds. This is not to say that everything was somehow great or that all ages are "equal" in "value" (whatever that really means), but you can not begin to study a period of history without facing your own preconceptions of it (and, really, your own society).
