Doesn't that depend on the medium? In a visual medium, in which there is no way of spinning a narrative between dialogue, there is no other choice but to have parts "narrated" that you can't find a place within the story for. Of course, even then you shouldn't just slap a lot of "World Building" into one chapter, because readers will tune out and skip most likely.
In a medium of purely written form, you shouldn't, at any point, "just narrate" anything. Neither a character nor a third person narrator should just rattle on forever about whatever happened in the past or is happening right now, unless a lot of things happen at the moment and truly need to be brought up in detail. Nobody's perfect, I know I've done it in the past and I couldn't erase it in my most recent story either, but when it comes to narration of lore and general world building, I'm trying to blend it in with events, have people explain more organically about things and break up narration into parts, so it won't hit and suffocate a reader to death. That's the best I could come up with, if a story requires a lot of lore to be explained.
No!
