EDIT.

I was underwhelmed at the beginning but after watching most of it, my opinion has changed.

It's quite entertaining and it keeps GoT atmosphere and flavour. It has interesting characters and some of them are full of charisma.

My main quibble with this show, it's that they are trying to compress years and years of plot in 8 episodes, when for the original GoT it was 8 seasons. Therefore, we had more time to know the characters and get invested. Plus, here the mystery factor that GoT had, is missing. And...why no one has mentioned Winter so far?

Anyway, it's good enough and I don't regret watching.
