The good:

- Tywin and that opening scene.
- Every Hound/Arya scene.
- The dragons! The possibility of Dany losing control of them is literally the only interesting direction her story looks to be going in right now.
- Oberyn

The bad:

- My first impressions of Daario's replacement are meh. The original actor in season 3 somehow managed to make him somewhat likeable.
- Jamie was disappointing. I felt they undermined his character development last season with his scenes in this first episode.

One Jamie moment I liked from the episode, which I didn't notice until I rewatched, was him waving at Qyburn with his new hand. Made me lol.
