I've said this many times before and I know it's super unpopular at this point but imo, NH dialogue is very good and is probably just below WW and the original GCN game. I don't remember seeing memorable dialogue in NL, not once. Most dialogue in NL was in the manner of, "go fetch me this; find me that; let's play this". NH dialogue is reminiscent of GCN. I also happen to read, in the most audacious ways, that NH dialogue is too repetitive. As opposed to what? People probably don't remember, but GCN and WW had repetitive dialogue as well. GCN especially (I fondly remember my villagers asking to trade something for their stuff or taking my stuff out of my pockets, but oh boy was it repetitive). And tbf, if you're logging in over 400 hours (like me), you'll eventually get more repetitive dialogue. But even know, I get dialogue I've never had before and Nintendo is probably adding even more dialogue to the game (depending on seasons; events, new characters and items, etc).
