The lead characters are great actors. Especially Petyr Baelish xD
The pacing and layout of each episode is great. It's very consistent with this. In case you were wondering whether or not you'll actually get to see some aliens and CGI UFOs in this - don't worry - you definitely will. Lots of them. But the way it is presented, it's like you aren't sure whether what you've seen is real, because it's from the point of view of people, in their recounts and stories.
