House of the Dragon teaser trailer (GoT prequel)

Which is funny because I really enjoyed it.
We learned nothing new, the story pretty much stood still from episode 1.

Alicent Hightower - Alicent Hightower...duh
Otto Hightower - wanna be puppet master...duh
Christan Cole - P-whipped, sucker for love *** trick...duh
Daemon, Aegon II & Aemond T - Loss the flip of the Targaryen coin...duh

I expected them to show more progression of the story considering this was a 68min episode.
