This is difficult, because I think you have branded yourself so successfully already that for me Hal is a feeling and not a set of labels. That sounds a little weird but I can't think how else to explain it just now.

But I'll give this a try: the right words, and not one more. Sympathy and affection for the characters even when you torture them. Short, funny, (haha and/or peculiar as someone else said), clever. Clearly presented and well-distributed. Surprises that also make sense.
