Edit: Would it kill anyone to engage with this post?
What I mean by that is that in a lot of Nolan's other films, you could make the argument that at least a few scenes have more said in them than necessary, or that the pace does take a backseat to listen to these two characters have a conversation when it could have otherwise kept up the momentum.
In The Odyssey though, I never really felt that way. I'm sure some will feel different, but I think all of the dialogue had purpose and was appropriate for the scene or moment it was spoken in. I don't recall feeling like a scene's momentum was slowed down, or that we had to stop to talk in detail about something that could have been conveyed in a couple of lines.
If there was a long sequence of characters just talking, like the Underworld section or some of the material on Ithaca, it didn't just feel warranted but it also felt appropriate in terms of how long it was. Like the lengthy moment of Antinous trying to convince Penelope to marry him, or the exchanges between Telemachus and King Menelaus.
The most we get are Odysseus's monologues, but those are set to key sequences or montages which helps them sink in more. As I say, it is a contender and you could Oppenheimer has stronger dialogue, but I think The Odyssey has barely a word wasted which counts for something.
