unfortunately, the majority of haggadahs have nothing to do with the mitzva of vehigadita levincha. Many are just a collection of stuff very loosely related to the text. The Lekach tov haggadah (I think its only in Hebrew) has the best focus on the real theme of the evening-imparting emunah lessons to our children through the experience of Yitzias mitzrayim. I wish someone like Rabbi David Ashear would make a haggadah incorporating his lessons into lessons from yitziat mitzrayim.
