This doesn't feel like a pilot episode, more like a mid season filler.

Half the music including the very first notes we hear and the last are actual scores from GOT, which are clearly bait. The end scene also calls out to GOT when it's simply not needed, another bait.

The sex and violence seemed unnecessary and misplaced. Half the episode is about the tourney.

Matt Smith takes me out of the world by having such a familiar face, though his arrogant acting successfully makes you hate Daemon Targaryen from the first.

The CGI is a bit much, including the colour palette. Feels like an early 2000s film.

I've read the book this story is from, and for those who haven't, if the show becomes as exciting as the story then do watch it, but I feel like the conquest of the seven kingdoms and the arrival of the Targaryens in Westeros would have been way more exciting.
