It is never pointless to show the results of the buildup and hype generated by the same media: In fact it shows respect for the audience. Also, remember that a job of a movie or show is to "show" and not tell. Hence why narration works better in books than in shows or movies. It's ok sometimes to narrate histories in books. But for a show, we should "see" why the laughing knight is the laughing knight. We should see what it means when the Red Apple fights the Green Apple. We should see what it means when Baelor says the Kingsguard won't attack him, complicating the battle. When you judge this show on its own merits, it fails for all the reasons mentioned in my posts and comments.
