Was reading an article about autism (in Time), when this sentence grabbed me: But then autism research took a badly wrong turn.

"Badly wrong?" Is it just me or is this particular usage exceedingly strange? - not to mention flat-out (even badly?) wrong. Can something also be goodly wrong?

I bow to superior word wizards : What say you-all? What's really scary is that the more I read it the less wrong it seems.
