Here is a short vort on the parsha to repeat at the shabbos table:

“Why doesn’t the Torah state ‘Ki Tov – It was good’ – after the creation of man, as it does after all the other things created during the six days?  Because every other creature was created complete, with its nature and instincts ready to be applied to the world.  Man, however, is given free will and the responsibility for his own development and improvement.  Thus, it doesn’t state, ‘and it was good,’ because we must wait and see how man behaves before passing judgment.” ~ The Kli Yakar (Torah Tavlin)
