Personally, it’s Faith from Farcry 5 for me. Uninteresting dialog that can be summed up to “I was bullied once” and that’s it. Literally every other character is so much more interesting. Jacob gives you a sequence where you run through a gulag which he then uses against you, John tries to kill you and is openly hateful towards you plus is a character you get to interact with, and Joseph is a lunatic who was right.
Zelda’s ghost in Spirit Tracks is even worse. She explains logic that a 5 year old could figure out. “Now we should go over there and do the obvious thing! I’m going to explain this over several sentences making you wait and click through them all!”
