The hagadah (based on the discussion of Rav and Shmuel in pesachim) dedicates the bulk of maggid to expounded the verses of arami oved avi. But why is there very little discussion of the actual miracles (mainly the plagues) that took place as part of the exodus? We only have passing mentions of the plagues with no elaboration or additional midrashic material offered.
This stands in contrast to other holidays such as chanukah or purim where the focus is on the miraculous nature of divine salvation. Furthermore it seems to undermine the nature of the chag as a conduit from one generation to the next (v'higadeta l'bincha). Children are excited by miraculous tales by nature yet we seem to go out of our way to avoid talking these miracles in the hagadah. Why?
