Terrible story (especially compared to prior games)
pointless mechanics that range from utterly useless to removing all challenge
the "emblem rings" are shoehorned into the game to bait nostalgia (which didn't even work)
over sexulazation of female characters (especially the children)
a main character that's somehow more incompetent and useless the Corrin
cut-scenes look very dumb (when not done in CG)
to name a few
