I thought the episode was pretty darn great. That beetle conversation, though...? ugh. Felt like it was killing time. To me, it didn't feel like foreshadowing, nor was it revelatory about character. It just felt like an insert for two great actors to monologue because they needed to fill a gap. For me, it was one of the few times they've taken a liberty on the show (I don't remember this scene in the books, but I could be wrong), and it didn't necessarily pan out. Normally GoT monologues are fantastic little morsels. The Oberon/Tyrion 'underwhelming' monster monologue was beautiful (and directly from the books).
As someone previously said, I'd have rather they filled the time with a scene of Oberon announcing his intentions to Cersei and Tywin.
Regardless, it's nitpicking. Still a fantastic episode.
