onto something

Suppose someone criticizes a certain view, and his criticism makes some sense but not totally right. In this kind of case, I heard people saying something like, "his criticism is onto something but not totally right."

Is this a correct use of "onto something"?

    Yes, though it's not specifically related to criticism. You're onto something if you've got an idea which is not quite right, but which looks promising: it seems to be the right direction to follow.
