It's just good enough to watch it. Pilot and episode 5 were good. Same Season 1 GOT, where Ep. 2-4 were setting the plot. But everything feels a little worse:

Too few characters, so no suprises and crazy fan theories. Yes, it's house of dragon and focuses on them. But 2-3 more secrets and betrayals to work from would be bettery

Most of the people kinda get along and just chill in their noble bubble. Exactly 1 ingrigue/secret is the theme from now on and it came by episode 5.

The cast is ok, GOT cast was genius.

Feels like they picked all the second choices from GOT. Yes, it takes time to grow into chracters, even if they are charismatic. It's ok.
