Good writing means that the dialogue fits the character, it means that the story doesn't crumble on itself, it means that it is interesting to hear about and the characters have good things to say. If they decide to tell you the story via exposition instead of subtle nuances why would that mean it's bad? They don't need to all follow the same patterns for story-telling to be good.
Expositions in dialogue are frowned upon because it's the easiest, laziest way to convey information. You can argue that the story itself is good, but how they convey it is also a big part of what good writing is. If you want to argue that it's a stylistic choice, then I'm curious how do you think the story is served positively by having long, heavy-handed and thematically redundant monologues at every turn.
